| 摘 要： | 为了提高吞吐量，无线通信系统要根据信道条件自适应地调节纠错码的码率和码长．根据多边类型低密度奇偶校验码的“多边”结构，提出“分级分层”的扩展算法，实现码率在0．2到0．5范围内可自适应调节的码率自适应MET-LDPC码．加性高斯白噪声信道下，所设计的Rc—MET—LDPC码应用于HARQ通信系统中，具有更好的误帧率和吞吐量．

| Abstract: | In order to increase the throughput, the wireless communication system needs to be adaptive in adjusting the rate and code length of error correction codes according to channel conditions. A hierarchical extended algorithm based on the multi-edge structure of the Multi - Edge Type Low Density Parity Check is proposed to obtain the rate compatible MET-LDPC code over a code rate range from 0. 2 to 0. 5. Simulation over AWGN channels show that the proposed RC-Met-LDPC code has superior performance on frame error rate and throughput in the HARQ communication system. |
