| 摘 要： | 本文构造了一种适用于中继协作通信的非正规LDPC系统码，并将双非正规LDPC系统码应用于中继协作系统中. 提出了目的点接收机基于双LDPC码联合Tanner图的对多路接收信号进行联合迭代译码的新算法. 理论分析和数值模拟表明本文所提出的新方法将高效信道编码和协作技术有机地结合起来以充分实现编码协作所具有的潜在分集和编码增益，与非协作系统相比可显著地提高系统性能.

| Abstract: | We propose a kind of simple-encoding irregular systematic LDPC codes suitable for relay cooperation.The constructed double LDPC codes are then applied to one-relay cooperation.The authors also suggest a new joint iterative decoding algorithm performed at the destination node for multiple received signals based on the joint Tanner graph for the double LDPC codes.It is demonstrated by theoretical analysis and numerical simulations that the proposed approach can well combine the techniques of high-efficiency c... |
