摘要：
A new scheme combining Adaptive Turbo Coded Modulation (ATuCM) and multicarrier transmission is proposed for high-bit-rate and high-quality Direct Sequence Code Division Multiple Access (DS-CDMA) systems. The total subcarriers are divided into L sub-bands each of which is composed of P adjacent subcarriers and the same Turbo Coded Modulation (TuCM) mode is employed for all the subcarriers in the sub-band based on subband channel estimation. Simulation results show that the proposed system can provide noticeable BER and throughput performance improvement on frequency-selective fading channels in comparison with the non-adaptive system.
