Abstract

This paper proposes a novel signal scheme called “hybrid OFDM/CDMA/SFH approach” which combines OFDM with CDMA and SFH to generate a system functionally superior to MC-CDMA systems. The paper describes the merits and demerits of the proposed system and compares it to the MC-CDMA system. Finally, we present simulation results in AWGN and fading channels with perfect and imperfect estimation
