This paper investigates the performance of channel estimation techniques applied to a proposed fourth generation (4G) multi carrier - code division multiple access (MC-CDMA) system. Coherent detection requires a per-sub band estimation of the channel frequency response for each coded orthogonal frequency division multiplexing (COFDM) symbol. This paper compares the performance of a number of pilot symbol assisted modulation (PSAM) methods for achieving such estimates. Performance results are characterised by bit-error-rate (BER), data throughput (DT) and mean-squared error (MSE) for ETSI UTRA specified channel environments. It is shown that in an indoor environment, FFT filtering provides superior data throughput performance, whereas in a high Doppler vehicular environment, a reduced complexity Wiener filter is able to offer the best performance.
