卷积码的编码与维特比译码的相关仿真

function [next_state,memory_contents]=nxt_stat(current_state,input,L,k)
binary_state=deci2bin(current_state,k*(L-1));%十进制数x转化为二进制数
binary_input=deci2bin(input,k);
next_state_binary=[binary_input,binary_state(1:(L-2)*k)];
next_state=bin2deci(next_state_binary);
memory_contents=[binary_input,binary_state];
