The software defined radio as a platform for cognitive radio
Pablo Robert and Bruce Fette
2.4a.1 Introduction
This chapter explores both the hardware and software domains of software defined radio (SDR). The span of information covered is necessarily broad; therefore, it focuses on some 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 can sample a maximum bandwidth, and a processor can provide a maximum number of million instructions ...
