  • Introduction

    Power line communications (PLC) reuse existing infrastructures (i.e. power lines) whose primary purpose is the delivery of AC (50 Hz or 60 Hz) or DC electric power, for the purpose of data communications. This introductory chapter provides the terminology that has been used to describe PLC. Communication over power lines is referred to by different names that are often specific to the considered grid domain and application. The most commonly used terminologies: carrier‐current systems, power line carrier, distribution line carrier (DLC), broadband over power lines (BPL) and power line telecommunications (PLT). Modern PLC systems use the latest signal processing techniques including advanced concepts such as multicarrier modulation with adaptive notching and multiple‐input multiple output (MIMO) transmission, which have already been adopted in international standards and industry specifications. The chapter presents an overview of how the other chapters of the book are organized.

  • Bipolar Power Switching Devices

    This chapter deals with three-terminal bipolar power switching devices. We begin with the bipolar junction transistor (BJT), discussing effects such as saturation and quasi-saturation, second breakdown, the Rittner effect, and the Kirk effect. We then consider the insulated-gate bipolar transistor (IGBT), essentially a merged BJT, and metal-oxide-semiconductor field effect transistor (MOSFET). Here we present a new derivation of the static characteristics and discuss the physical mechanisms that limit switching performance. We conclude with a discussion of thyristors and gate-turn-off (GTO) thyristors, including triggering, quenching, and transient response.

  • Algorithmic Methodologies for Discovery of Nonsequential Protein Structure Similarities

    This chapter discusses several issues of structural alignment. It then focuses on methods implemented for sequence order-independent structural alignment at the global and local surface levels. The chapter illustrates the utility of these methods by showing how the sequence order-independent global structural alignment method detects circular permuted proteins. The chapter shows how the local surface sequence order-independent structural alignment method can be used to construct a basis set of signature pockets of binding surfaces for a specific biological function. The chapter also describes the details of the circular permutation found between a neucleoplasmin core and an auxin binding protein, as well as details of the more complex noncyclic permutation. The chapter further shows that the surface alignments can be used to automatically construct a basis set of signature pockets representing structurally preserved atoms across a family of proteins with similar biological functions.

  • Voice Evolution

    WCDMA/HSPA radio offers a number of options for enhancing voice service. Voice quality can be improved with AMR wideband codec, voice capacity can be improved with AMR narrowband lower rate codecs and voice can be carried over HSPA as Circuit Switched (CS) or Packet Switched VoIP Service. These solutions are described in Voice evolution chapter. The voice interworking with LTE is also presented including CS fallback (CSFB) solution and Single Radio Voice Call Continuity (SRVCC) from LTE VoIP to WCDMA CS voice.

  • Spectral Activity Detection in Wideband Cognitive Radios

    This chapter focuses on the problem of detecting unknown signals located at unknown carrier frequencies over a possibly wide spectrum subband. This is called the wideband spectral activity detection problem. Signals and noise were assumed to be Gaussian, and the approximate decision statistic was based on sinusoidal signals in low SNR region. With a wider spectrum band, it is more likely that the sensed signal Y may contain a mix of heterogeneous spectral activities from a variety of electromagnetic sources leading to outliers, jammers, and interferers that can better be modeled as non‐Gaussian. In the case of wideband cognitive radio spectrum sensing, it is very likely that noise may not always be Gaussian. Compressive sampling (CS) is an efficient approach to reconstruct functions, or signals, that are sparse in a certain domain.
