Abstract
This chapter addresses various aspects of multicarrier modulation (MCM) techniques, and compares their performances. Parameters for the conceptual design of orthogonal frequency division multiplexing (OFDM) and multicarrier CDMA (MC-CDMA) systems are given based on the performance of communication link. The evolution of mentioned conventional MCM systems results in wavelet-based MC-CDMA systems, which are proposed in this chapter. With all the advantages of the conventional MC-CDMA, the wavelet-based MC-CDMA systems provide not only higher bandwidth efficiency than the conventional MC-CDMA systems, but new dimensions for the anti-fading and interference immunity by the suitable choice of the wavelet functions and the wavelet frequency bands. By the results, wavelet-based MC-CDMA can be the one feasible candidate for the applications in future public land mobile telecommunication systems (FPLMTS)/international mobile telecommunications (IMT) - 2000 and mobile multimedia.
