Chapter 1. Introduction
The aim of this book is to present the key underlying signal-processing principles used in software-defined radio (SDR) analysis and design. The various chapters span topics ranging from analog and digital modulation to radio frequency (RF) and digital signal processing and data conversion. Although the intent is to cover material relevant to the signal processing used in SDR, the same material could be applied to study more traditional radio architectures.
1.1. The Need for Software-Defined Radio
The SDR forum[1] defines SDR as a “radio in which some or all of the physical layer functions are software defined.” This implies that the architecture is flexible such that the radio may be configured, occasionally in real ...
