Abstract

Multi-carrier code division multiple access (MC-CDMA) is one of the best candidates for the future broadband wireless multimedia communication systems. This paper proposes a novel channel estimation algorithm for MC-CDMA systems on the uplink. With reasonable constraint and well-designed preambles for each user, the DFT-based uplink channel estimation algorithm can achieve good estimation accuracy without sacrificing much system capacity. Computer simulation demonstrates the effectiveness of this method and our conclusion is presented.
