The techniques proposed for joint denoising and compression of images corrupted with additive white Gaussian noise are mostly based on Rissanen's minimum description length principle and tend to operate at a particular point (or a set of points) on the rate-distortion curve. These offer some compression along with denoising, but not a practical encoding solution. This paper suggests a simple ...

  • Correlator Output SNR, Effective C/N0, and I/S

    The combination of signals, noise, and interference at the receiver input affects correlator output signal-to-noise ratio (SNR), an important measure of receiver performance. This chapter describes the concept of correlator output SNR and defines it rigorously, leading to the important concepts of effective C/N0 and processing gain. It discusses the severity of an interference environment in terms of the interference power-to-signal power ratio, or I/S and also describes the conversion between effective C/N0 and I/S. The resulting tools can then be extended and applied to assess the effects of multiple access interference (MAI) from a given constellation, and even from a number of constellations. Correlator output SNR is the primary metric used to assess receiver performance in interference, and expressions for correlator output. Spectral separation coefficients (SSCs) are a powerful tool for assessing the effect of interference on correlator output SNR.

  • Introduction to Modulators: Basic Concepts and Fundamentals

    This chapter is conceived as an introduction to CMOS Sigma-Delta (?>?>) analog-to-digital converters (ADCs). Their operation principle consists in combining oversampling, quantization error processing, and negative feedback for improving the effective resolution of a coarse quantizer. Before presenting practical topologies for the implementation of ?>?> modulation, the large variety of the existing ?>?> realizations is briefly classified according to the type of modulator architecture (single loops or cascades), the circuit techniques employed (discrete time (DT) or continuous-time (CT)), and the nature of the signals being converted (low pass (LP) or band pass (BP)). Starting from the case of DT, LP, single-bit ?>?> modulators, the implications of these different alternatives are then presented in an incremental way.

  • Introduction

    This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book explores how should efficient signal coding work when very narrow bandwidths per bit are available. Communication transmits messages through time and space. In communication engineering, sending a symbol has three basic costs: energy, bandwidth, and implementation complexity. Coding, bandwidth, and their interaction lie at the heart of this book. The book is about efficient transmission via coding when the relative bandwidth is narrow. Most modulators in use today are pulse modulators, meaning that they associate each symbol with a pulse. The chapter also discusses spectra of modulated signals and the error performance and optimum receivers. Not all modulations produce simple pulses and the need to reduce bandwidth can lead to rather complicated signals. It can be a subtle exercise to distinguish coding from modulation, especially when bandwidth plays a role.
