摘要
Reed-Solomon(RS)码是一种非二进制循环码,具有优良的纠随机错误和突发错误的能力,在卫星通信、数据存储等诸多方面中有着广泛应用。而在无线通信系统中,无线信道的衰落是影响系统性能的重要因素,协作技术则是对抗衰落的有效手段。论文首先对RS码的编码原理及欧几里得译码算法进行了简要介绍,并在此基础上提出了一种基于RS码和二进制线性分组码相结合的中继协作分集机制和基于信噪比阈值判断的联合译码方案,并对其进行了理论分析和Matlab性能仿真。仿真结果表明,在不同的中继信道条件下,该系统方案得到了不同程度的性能提升。
The Reed-Solomon(RS)code is a non-binary cyclic code with excellent ability to correct random errors and burst errors. It is widely used in satellite communication,data storage and many other fields. In wireless communication systems,the fading of wireless channels is an important factor affecting system performance,and cooperative technology is an effective means of combating fading. Firstly,the encoding principle and the Euclidean decoding algorithm are introduced briefly. Based on this,a relay cooperative diversity mechanism based on RS code and binary linear block code and a joint decoding scheme based on SNR threshold judgment are proposed. The theoretical analysis and Matlab performance simulation are carried out. The simulation results show that the scheme achieves different levels of performance improvement under different relay channel conditions.
