| 摘 要： | 提出一种采用LDPC乘积码和BICM-ID相结合的编码调制技术.该方案编码采用LDPC乘积码,译码可以采取三个迭代过程:在解调器和译码器之间迭代,LDPC乘积码的分量码之间迭代,以及分量码内部迭代.因此采取合理的迭代译码策略,可以提高的译码效率.仿真结果显示,该方案在AWGN信道和Rayleigh信道条件下,与数字电视地面多媒体广播DTMB采用的编码调制方案相比具有更好的误比特性能.

| Abstract: | In this paper,the BICM-ID programme is presented based on LDPC product code.The programme uses LDPC product code.The decoding can take three iterative process,the iteration between the demodulator and the decoder,the iteration of component codes of LDPC product code,and internal iterative of component codes.Therefore,by taking reasonable iterative decoding strategy,the efficiency of the decoding can be improved.The simulation results show that the programme has a good bit error performance under the conditi... |
