摘要:
比特交织编码调制迭代译码(BICMID)是一种编码、调制和迭代译码相结合的技术,主要应用于无线通信中的信道编译码.BICMID在结构设计上加入了比特交织器和软输入软输出(SISO)译码器,结合迭代译码,最终实现次优译码.不同的编码方法在BICMID系统中也有着很大的性能差异,针对几种常见纠错编码方法——卷积码、Turbo码、LDPC码,在BICMID系统下的误码率性能进行比较.仿真得到系统在AWGN信道和Rayleigh衰落信道下的误码率曲线,表明不同纠错编码的BICMID系统性能与理论分析相一致.
Abstract:
Bit-interleaved coded modulation and iterative decoding (BICMID) is a technology of combining coding, modulation and iterative decoding, mainly used in wireless communication. In the structural design, BICMID has bit interleaver and softinput softoutput (SISO) decoder, and is combined with iterative decoding, which can ultimately achieve suboptimal decoding. Different coding ways in the BICMID are also very different in performance. This paper presents a comparison of several common methods of error correction coding, such as convolutional codes, Turbo codes, and LDPC codes in the BER performance of BICMID system. Simulation results demonstrate the bit error rate curves of BICMID system in the AWGN channel and Rayleigh fading channels, so a conclusion can be drawn that the performance of BICMID system with different errorcorrecting codes is consistent with the theoretical analysis.
