Abstract

Abstract: Proposes a novel channel estimation algorithm for multi-carrier codedivision multiplex access (MC-CDMA) systems on the uplink. With reasonable constraint and the assistant of special-designed pilot sequence for each user, the discrete fourier transform (DFT)-based uplink channel estimation algorithm can achieve good estimation accuracy without sacrificing much system capacity. Simulation results show the good performances of this method.

Key words: :orthogonal frequency division multiplexing, channel estimation, uplink
