- 摘要:
- 为改善低密度奇偶校验(LDPC)码的量化译码算法的译码性能,提出了一种改进的4比特量化偏移最小和(OMS)译码算法.改进的OMS译码算法中对接收信号和后验信息进行了量化处理.仿真实验表明,在高信噪比情况下,与接收信号4比特量化相比,改进的量化OMS译码算法可以降低误码率.
- Abstract:
- In order to improve decoding performance for quantization decoding algorithm of low density parity check(LDPC)codes, an improved 4 bit quantized offset min sum(OMS)algorithm was designed. The improved OMS algorithm is obtained by quantizing the received signal and the posterior information. The simulation results show that the bit error rate for the improved OMS algorithm were down more than from 4 bit quantization of the received signal at high SNR.
