Abstract :
The performance achievable with turbo codes for MC- CDMA in fading channel has been recently reported [C. Ghosh et al., 2003]. Further performance gain can be achieved by jointly using turbo decoding and multiuser detection. Turbo decoding in combination with detection strategy for multi-access interference (MAI) cancellation has been shown to be very effective for MC-CDMA system in Rayleigh multipath fading environment. This paper reports new simulation results on the efficacy of joint decoding and detection for MC-CDMA in a nonlinear and fading channel.
