摘要 提出一种基于高阶星座调制的高效编码协作方案.用户或协作伙伴的编码比特分组后分别通过比特交织器,之后映射到高阶二维星座按分配时隙发送.推导了该协作方案在慢瑞利衰落信道下的成对错误概率.理论分析以及仿真结果都表明,慢瑞利衰落信道下,本方案在提高频谱效率的同时可获得完全分集. A high-efficient coded cooperative （CC） scheme with high-order constellations is proposed. In this scheme, encoded bits of the user or the partner are partitioned, bit interleaved, mapped on a highorder two-dimentional constellation and then transmitted on the allocated time slots. The pairwire error probability over slow-fading Rayleigh channels are derived. Both theoretical analysis and simulations show that the coded cooperation with high-order constellations can achieve full diversity with an improved spectrum effciency over slow-fading Rayleigh channels.
