这是关于LDPC信道编码模块设计的程序
打开源程序,先运行gengrate_h.m程序,陆续将码长设置为756bit,列重设置为3,行重设置为9。在Workspace中同时将H、A、B、C、D、E、Hget、Fget、g、Tget这是个变量选择另存为encode_in.mat 格式。再运行main_encode.m进行编码,主程序运行后,在当前目录下,自动生成编码结果文件“encode—out.mat”,这将作为下一次扩频调制仿真实验的的输入信号。最后分别查看Workspace中的变量s

直接序列扩频Matlab程序源码 直接序列扩频通信能有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在在接收端,原伪噪声序列与所收信号的的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声;同时,将DS信号解扩,恢复原始信息数据。 可直接使用。
