MPSK----TCM的MATLAB仿真 求救

8psk程序，对不？请教高人

bit_sequence=rand(1,N)>0.5;
bpsk=bit_sequence*2-1;
temp=[1+j -1+j -1-j 1-j]/sqrt(2);
transformbit = [0 0];
qpsk_sequence = ones(1,N/2);
for k=1:N/2
transformbit = bit_sequence(2*k-1:2*k);
if transformbit== [0 0 0]
qpsk_sequence(k) = temp(1);
end
if transformbit== [0 0 1]
qpsk_sequence(k) = temp(2);
end
if transformbit== [0 1 0]
qpsk_sequence(k) = temp(3);
end
if transformbit== [0 1 1]
qpsk_sequence(k) = temp(4);
end
if transformbit== [1 0 0]
qpsk_sequence(k) = temp(5);
