Abstract

This chapter focuses on the application of spectral diversity via transform domain (TD) waveform design instead of the traditional time domain formulation. The basic idea behind TD waveform design is to address interference at the transmitter and thereby minimize signalprocessing complexities at the receiver [3]. This approach is generalized within the spectrally-modulated-spectrally-encoded (SMSE) framework and includes all multicarrier waveform designs such as orthogonal frequency division multiplexing (OFDM) and multicarrier code-division multiple access (MC-CDMA) [4,5] as special cases. These multicarrier SMSE waveforms are utilized in the design of overlay and underlay cognitive radio waveforms. The vast majority of existing research on physical layer spectrum coexistence addresses cognitive radio systems, where the focus is mainly on the sharing of spectrum between multiple communication systems [2,6,7]. In this chapter, we introduce the foundational work for a transform domain communication system (TDCS) and SMSE framework, and then discuss the design of multicarrier communication and radar waveforms based on SMSE.
