Design and performance of OFDM-CDMA system in fading channels

Effect of Comb type channel estimation on performance of MC-CDMA

“…Multicarrier Code Division Multiple Access (MC-CDMA) is a candidate for mobile systems to take advantage of the robustness of OFDM to multipath propagation and the flexibility of CDMA technique [2,3]. The performance of MC-CDMA system is analyzed using carrier frequency offsets in correlated multipath fading [4], in Rayleigh fading channels with correlated envelopes and phases [5], over frequency-selective Nakagami-m fading channel with correlated and independent subcarriers for the uplink scenario and Maximal Ratio Combining (MRC) reception [6] and the performance of OFDM-CDMA and CDMA systems in fading channels for the downlink is also studied [7]. Recently, the performance of MC-CDMA over influence of frequency selective generalized Ș-ȝ fading environment is studied in [8].…”
