space_time.m

一些关于空时编码的编码解码仿真程序

function  [out] = space_time(input_bit)

[K,N,G,N_t,N_r,L]= header;

input = zeros(1,2);

%[msg] = source;
%input_bit = msg;
st_code = zeros(N_t,N*K);
former_state = 0;
for m = 1:N*K,
    input = input_bit(1,2*m-1:2*m); 
    [output,states] = psk_trls(input,former_state);
    st_code(1,m) = j^output(1);
    st_code(2,m) = j^output(2);
    former_state = states;
end

out = st_code;
