Abstract

Generalized multi-carrier (GMC) CDMA transceivers equipped with frequency hopping are developed in this paper. Through judicious code design, multiuser interference (MUI) is eliminated deterministically and symbol recovery is guaranteed, relying on a minimum number of redundant subcarriers. This, together with subcarrier frequency hopping (FH), improves BER performance in the presence of frequency-selective multipath fading channels and enhances resistance to narrow-band interference. Blind channel estimation methods are developed with guaranteed channel identifiability, regardless of the locations of the zeros of the FIR channel. Performance analysis and simulation results illustrate the merits of the proposed FH-GMC-CDMA transceivers relative to competing OFDMA and multicarrier CDMA alternatives.
