摘要：
In this paper the performance of a Turbo coded OFDM/CDMA system with QPSK signal mapping under additive White Gaussian noise (AWGN) with no fading and with multi-path fading channel is analyzed and simulated. For Turbo codes, Max-Log -MAP algorithm is employed because it is a less complex sub-optimal algorithm for iterative decoding. Evaluation of the proposed receiver by means of computer simulation has shown substantial performance improvement for both non-fading and multi-path fading environments under AWGN.
