This chapter explores both the hardware and software domains of software-defined radio (SDR). The span of information that this chapter covers is necessarily broad; therefore, it focuses on some of the aspects of hardware and software that are especially relevant to SDR design. Beyond their obvious differences, hardware and software analyses have some subtle differences. In general, hardware is analyzed in terms of its capabilities. For example, a particular radio frequency (RF) front end (RFFE) can transmit up to a certain frequency, a data converter ...
