中文摘要：
为了在编码协作中有效地利用低密度奇偶校验（LDPC）码，提出了一种采用LDPC码的编码协作方案．理论分析了平坦衰落信道条件下该方案具有的分集增益及误码性能，并通过仿真验证了典型平坦衰落信道下该方案的性能．
英文摘要：
A new coded cooperation scheme based on LDPC codes is presented. The scheme is stated in detail to show how the LDPC codes is designed and used in the coded cooperation scheme. To verify its performance under flat fading channels, the diversity gain and bit error performance is deduced theoretically. And simulations about the performance of the new scheme under typical flat fading scenarios supports the theoretical analysis.
