搭建BPSK+编码+交织仿真通信链路
说明: 搭建 BPSK+编码+交织仿真通信链路,仿真分析在不同信道条件下的不同译
码算法的误比特率性能。基于 matlab,搭建 BPSK+卷积编码+交织通信收发链路,
仿真参数如下: 1) 信源比特速率: 100 b R kbps = 2) 卷积编码:码率为 1/2,生成多项式为(561,753) 3) 译码方式:维特比译码(硬判决译码、软判决译码(8 比特量化)) 4) 交织:行列交织,交织器深度为 100bit,宽度为 10; 5) 仿真点数:106 1. 在 AWGN 信道下,仿真并绘出该系统在硬判决和软判决(3bit 量化)两
种译码方式下的信源误比特率曲线,并进行分析。 2. 设定某种交织器结构,在单径瑞利衰落信道( 100 d f Hz = )下,采用理 想信道估计,仿真并绘出该系统在有无交织、不同译码方式(硬判决和 软判决)时,在不同 0 b EN下的信源误比特率曲线,并进行分析。 3. 改变交织器结构,选择三种不同的交织深度(自行决定),在单径瑞利衰 落信道( 100 d f Hz = )下,仿真并绘出该系统在不同交织长度时,在不 同 0 b EN下的信源误比特率曲线,并进行分析。(Build a BPSK + encoding + interleaving simulation communication link, and analyze the different translations under different channel conditions
