  • Superconducting Antennas

    This chapter contains sections titled: * Introduction * Superconductivity Concepts for Antenna Engineers * Dipole, Loop, and Patch Antennas * Phasers and Delay Lines * Superconducting Antenna Summary * References

  • Wireless Channel Impairment Mitigation Techniques

    Wireless channels cause many types of wireless channel impairments such as noise, path loss, shadowing, and fading, and wireless communication systems should be designed to overcome these wireless channel impairments. This chapter investigates the fundamentals of wireless channel impairment mitigation techniques. Diversity techniques mitigate multipath fading effects and improve the reliability of a signal by utilizing multiple received signals with different characteristics. C. Shannon predicts that it is possible to transmit information without errors over the unreliable channel and an error control coding technique exists to achieve this. Multiple Input Multiple Output (MIMO) techniques are classified into spatial diversity techniques, spatial multiplexing techniques, and beamforming techniques. Due to a time dispersive channel by multipath fading, Inter‐Symbol Interference (ISI) occurs and an equalizer plays an important role in ISI compensation. The Orthogonal Frequency Division Multiplexing (OFDM) system also has many advantages.

  • Cross‐Layer Resource Allocation and Scheduling

    The aim of this chapter is to justify the need for reduced‐complexity, reduced‐overhead and cross‐layer approaches to resource allocation, scheduling and channel estimation and to present some possible approaches. A resource allocation algorithm is first examined that employs chunks of subcarriers instead of individual subcarriers, thus resulting in reduced complexity and overhead. It is shown that, by appropriately choosing the chunk size as a function of the coherence bandwidth of the channel, the algorithm can be employed in Distributed Broadband Wireless systems without significant penalty. A cross‐layer user scheduling and resource allocation is then presented. The algorithm modifies previous approaches that had focused on the sum rate, in order to also provide Quality‐of‐Service guarantees. It is demonstrated that the algorithm can improve fairness and accommodate MAC layer requests at the cost of some additional control overhead. Finally, the problem of channel estimation is considered, which is of crucial importance for the operation of scheduling and resource allocation algorithms. A scheme that relies on careful placement of pilots and superposition of pilots to data symbols is proposed. It is shown that the scheme can reduce the overhead that is required for channel estimation. Moreover, the complexity for the hardware implementation of the scheme is considered.

  • Orthogonal Frequency‐Division Multiplexing

    The Orthogonal Frequency‐Division Multiplexing (OFDM) became the most popular transmission technique for a broadband communication system because it has many advantages such as robustness to multipath fading channels and high spectral efficiency. It allows multiple users to receive information at the same time on different parts of the channels. This chapter designs the OFDM system and discusses hardware implementation issues. The first design parameters of the OFDM system for wireless communications are Inter‐Carrier Interference (ICI) power, the size of the Discrete Fourier Transform (DFT), and the subcarrier spacing (or the OFDM symbol duration). The second design parameter is the guard interval and the cyclic prefix (CP). The third design parameter is the pilot subcarrier allocation. The fourth design parameter is windowing. The Fast Fourier Transform (FFT) and the Inverse Fast Fourier Transform (IFFT) are efficient algorithms to compute the DFT and IDFT.

  • Single-Channel Techniques for Information Extraction from the Surface EMG Signal

    This chapter describes some of the most commonly used techniques for processing single-channel surface electromyographic (sEMG) signals. The single-channel techniques address the interference pattern that results from the simultaneous activation of many motor units (MUs). The chapter reviews spectral estimation and traditional stochastic models applicable to the electromyographic (EMG) signal. These models are used to develop, interpret, and test most of the signal processing techniques. EMG amplitude estimates have been assessed via a common application: the use of surface EMG to estimate joint torques. The chapter explores the basic body of knowledge concerning EMG spectral analysis and how physiological parameters are reflected by surface EMG power spectra. It further focuses on the theoretical basis for the assessment of muscle fatigue during high-intensity isometric constant force contractions since this assessment is by far the most prevalent application of surface EMG spectral analysis.

  • When the Basics Aren't Enough: Finding a Comprehensive Editor

    While mechanical editing is good and necessary, but to produce quality documents, much more comprehensive editing is called. This chapter describes how to find technical editors who can make documents more than just good, editors who can think about the content of the message, not just its presentation. It lists six steps involved in comprehensive editing. They are reading the document through quickly; studying the outline or structure of the document; thinking about the document; reading the document carefully, checking whether the discussion is complete, for technical discrepancies and definition of terms; writing comments on the document; and meeting with the technical author. The chapter then illustrates, with charts, the difference between "mechanical" and comprehensive editing. It also discusses the attributes of a comprehensive editor, and concludes with the interesting question of how to identify job applicants who might have the characteristics to become good comprehensive editors.

  • IV Learning and Reasoning

    So far, we have explored the panoply of qualitative representations and how they can be used in reasoning and communication in a wide variety of tasks, providing evidence for their utility and for their psychological plausibility. We have already seen some examples of how such representations tie into other forms of conceptual structure, as in the discussion of how qualitative representations play a role in natural-language semantics in chapter 13 and the discussion of how qualitative representations play a role in high-level vision in chapters 14 and 16. Here we go further in explicating the roles for qualitative representations in human conceptual structure by looking three important topics:

  • How to Avoid the Transitional Ax in Indirect Bad News Messages

    Professional communicators and managers can soften the tone of bad news messages by avoiding "transitional axes", which are words and phrases that sever one section of the message from the next section. These words destroy any potential for goodwill between the sender and receiver of the message. The sender can avoid transitional axes in at least three ways: (1) by using verbally keyed transitions such as repeated words, synonyms, specific naming, abbreviations or generic nouns; (2) by using cognitively keyed transitions that employ word- and thought-association to create implied connections; and (3) by using traditional connectors such as conjunctions and conjunctive adverbs. By using any of these methods to avoid the transitional ax, one can find that the indirect bad news messages are more coherent, more positive in tone, and ultimately, more effective in doing a difficult job well while maintaining goodwill.

  • Reverse Engineering: The Outline As Document Restructuring Tool

    Outlining is usually thought of as an important tool for the initial stage of document development. This chapter focuses on perfecting longer documents. Outlining is a process that normally moves from researching and noting ideas, through outlining and writing, to revising. Engineering writers who use outlines and find that arranging concepts into an outline establish the relative importance of the concepts; ensure continuity of thought, lend proper structure, and promote document completeness. Assigning ideas to first-, second-, and lower-order headings means defining each section's limits and ensuring document coherence. Consecutively listing coordinate headings is a means of developing continuity. This procedure is based on the concept of reverse engineering. The chapter presents five steps to follow to use this kind of reverse engineering to analyze and restructure the document to improve its final coherence and impact. The most important advantage is the saving of time.

  • FREQUENCY SHIFT KEYING (FSK) MODULATION, DEMODULATION, AND PERFORMANCE

    This chapter focuses on binary frequency shift keying (BFSK) and several implementations of known or estimated frequency and phase information regarding the received signal. It discusses the detection algorithms for each of the knowledge‐based conditions. In each case, expressions for the theoretical bit‐error probability are developed that provide a baseline for simulated and hardware testing performance evaluations. The chapter includes several case studies that examine the performance sensitivities of specific implementations. The detection of BFSK‐modulated waveforms is accomplished in several ways without using complicated frequency acquisition and tracking algorithms. These techniques involve noncoherent detection methods wherein the implementation simplicity is traded for degraded performance. In the chapter, the spectral density of BFSK is evaluated for arbitrary modulation indices based on the work of R.R. Anderson and J. Salz. The chapter concludes with the characterization of the spectrum of BFSK for various modulation indices.
