基于MIMO-OFDM时间同步用LS算法实现Timing-synchronization

matlab源程序如下:

%...................................................................
clear all;
clc;
nloop=100;
SNR_loop = [-10:5:25];
for i = 1:1:length(SNR_loop)
SNR1 = SNR_loop(i);
[n01(i)]=conventional22(SNR1)
pe(i)=(nloop-n01(i))/nloop;
end
pe
grid on;
semilogy(SNR_loop ,pe,'*-- g','Linewidth', 2)
axis([-15 20 0.1 1 ])
hold on;
%................................................................
clear all;
clc;
nloop=100;
SNR_loop = [-10:5:25];
for i = 1:1:length(SNR_loop)
SNR1 = SNR_loop(i);
[n01(i)]=conventional33(SNR1)
pe(i)=(nloop-n01(i))/nloop;
end
pe
grid on;
semilogy(SNR_loop ,pe,'o-- g','Linewidth', 2)
axis([-10 25 0.1 1 ])
hold on;
%................................................................

pe(i)=(nloop-n01(i))/nloop;
end
pe
