  • Multiuser CDMA Fi-Wi Systems

    A multiuser CDMA fiber-wireless system will experience all the following impairments: (1) nonlinear distortions in the optical channel; (2) multipath dispersion in the wireless channel; and (3) multiuser interference in the air interface. Optical and electrical noise will also be added in both channels. In addition, each user will experience individual multipath fading while the nonlinear distortion would be a function of total number of users in the system because nonlinear optical channel is shared among them. This chapter shows how all these impairments can be estimated and equalized using a very interesting iterative technique. This algorithm could add value for fourth generation (4G) wireless networks.

  • No title

    This book is Volume IV of the series DSP for MATLAB™ and LabVIEW™. Volume IV is an introductory treatment of LMS Adaptive Filtering and applications, and covers cost functions, performance surfaces, coefficient perturbation to estimate the gradient, the LMS algorithm, response of the LMS algorithm to narrow-band signals, and various topologies such as ANC (Active Noise Cancelling) or system modeling, Noise Cancellation, Interference Cancellation, Echo Cancellation (with single- and dual-H topologies), and Inverse Filtering/Deconvolution. The entire series consists of four volumes that collectively cover basic digital signal processing in a practical and accessible manner, but which nonetheless include all essential foundation mathematics. As the series title implies, the scripts here will run on both MATLAB™ and LabVIEW™. The text for all volumes contains many examples, and many useful computational scripts, augmented by demonstration scripts and LabVIEW&# 482; Virtual Instruments (VIs) that can be run to illustrate various signal processing concepts graphically on the user's computer screen. Volume I consists of four chapters that collectively set forth a brief overview of the field of digital signal processing, useful signals and concepts (including convolution, recursion, difference equations, LTI systems, etc), conversion from the continuous to discrete domain and back (i.e., analog-to-digital and digital-to-analog conversion), aliasing, the Nyquist rate, normalized frequency, sample rate conversion and Mu-law compression, and signal processing principles including correlation, the correlation sequence, the Real DFT, correlation by convolution, matched filtering, simple FIR filters, and simple IIR filters. Chapter 4 of Volume I, in particular, provides an intuitive or "first principle" understanding of how digital filtering and frequency transforms work. Volume II provides detailed coverage of discrete frequency transforms, includi g a brief overview of common frequency transforms, both discrete and continuous, followed by detailed treatments of the Discrete Time Fourier Transform (DTFT), the z-Transform (including definition and properties, the inverse z-transform, frequency response via z-transform, and alternate filter realization topologies including Direct Form, Direct Form Transposed, Cascade Form, Parallel Form, and Lattice Form), and the Discrete Fourier Transform (DFT) (including Discrete Fourier Series, the DFT-IDFT pair, DFT of common signals, bin width, sampling duration, and sample rate, the FFT, the Goertzel Algorithm, Linear, Periodic, and Circular convolution, DFT Leakage, and computation of the Inverse DFT). Volume III covers digital filter design, including the specific topics of FIR design via windowed-ideal-lowpass filter, FIR highpass, bandpass, and bandstop filter design from windowed-ideal lowpass filters, FIR design using the transition- band-optimized Frequency Sampling technique (impleme ted by Inverse-DFT or Cosine/Sine Summation Formulas), design of equiripple FIRs of all standard types including Hilbert Transformers and Differentiators via the Remez Exchange Algorithm, design of Butterworth, Chebyshev (Types I and II), and Elliptic analog prototype lowpass filters, conversion of analog lowpass prototype filters to highpass, bandpass, and bandstop filters, and conversion of analog filters to digital filters using the Impulse Invariance and Bilinear Transform techniques. Certain filter topologies specific to FIRs are also discussed, as are two simple FIR types, the Comb and Moving Average filters.

  • Phased Arrays

    This chapter discusses the particular problems of phased arrays by considering the effects of phase shifters and feed networks. Fixed phase shifters cause the beam to scan as frequency changes and limits bandwidth or can be used to scan a series fed array. Phase shifter quantization causes sidelobes and errors reduce gain. Element position or existence taper is used to reduce sidelobes. Constrained corporate or space feeds are analyzed. Adaptive array nulls reduce interference and can improve radar or communication systems (smart antenna).

  • Fundamentals of Signal Transmission on Interconnects

    This chapter presents the major concepts required to understand the movement of signals on transmission lines. The important concept of traveling waves is introduced and the origin of reflections on transmission lines identified. The concepts discussed in the chapter include packaging hierarchy, primary and secondary transmission constants, and transmission line impedances. Interference between the incident and reflected waves, traveling at the same velocity but in opposite directions, causes a ¿¿¿standing¿¿¿wave¿¿¿ field pattern to be set up. If there is a signal current there must be a return signal current which will tend to be as close to the signal current as possible to minimize stored energy. The provision of a signal return path is important in maintaining the integrity (i.e., predictable signal waveform) of interconnects. A range of models are used for interconnects depending on the accuracy required, the amenability of the net to modelling, and the frequency of operation.
