DFT-Based Channel Estimation for Uplink MC-CDMA
Wenbo Wang · Beijing Youdian Xueyuan xuebao · 2004
Proposes a novel channel estimation algorithm for multi-carrier code division 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.
