decoding_conv.m

一些关于空时编码的编码解码仿真程序

function [out] = Decoding_conv(in)
[K,D,N,G,N_t,N_r,L]= header;

tblen = 3; % Traceback length
% Use hard decisions.
tre  = poly2trellis(3,[6 7]);
decoded = vitdec(in,tre,tblen,'cont','hard');

M=2;
out = zeros(1,D*M*N/2);
out(1:D*M*N/2-tblen) = decoded(tblen+1:D*M*N/2);
