摘要
基于TMS320C6416高性能通用DSP,实现了对AWGN信道的信噪比(SNR)估计,并以此估计值设计了一种低密度奇偶校验(LDPC)码的译码系统;详尽介绍了集成SNR估计的译码系统的实现方案和流程;仿真结果表明,此估计下的译码器具有较好的性能。
A decoding system of LDPC (Low Density Parity-Check) integrated SNR-Estimation over the AWGN (Additive White Gaussian Noise) channel is designed and implemented using TMS320C6000, a high performance general purpose DSP. The realization scheme and workflow of system and the SNR-Estimation method are discussed in detail. The extensive simulation results show that decoding system with this SNR-Estimation has a good performance.
