Chapter 4. High-Level Requirements and Link Budget Analysis

An ideal SDR offers a highly flexible and versatile platform that permits the instantiation of a variety of different waveforms^[1] with widely varying specifications. More precisely, the radio must be capable of transmitting and receiving over a wide frequency range, at various power levels and bandwidths, using different modulation and multiple access schemes. The radio must also be capable of supporting various applications ranging, for example, from simple landing aid waveforms and secure voice communication to advanced data messaging or multimedia application over ad-hoc networks. This versatility imposes on the SDR multiple sets of requirements that must be met all in one platform. ...
