【MATLAB】AWGNで送信するための関数

MATLAB

Posted at 2018-10-15

function [ RX ] = AWGNchannel( TX,EbNo,M )
%TX:送信シンボルベクトル
%M=多値数　QPSKなら2,16QAMなら4,64QAMなら6
temp_size = size(TX);
SNR = M*10^(EbNo/10);
No = 1/SNR;
noise = normal_rand(sqrt(No/2),temp_size(1),temp_size(2)) + 1j*normal_rand(sqrt(No/2),temp_size(1),temp_size(2));

RX = TX + noise;

end


function [ output_args ] = normal_rand( sigma,height,width )
%sigma:生成したい正規分布の乱数の標準偏差
    output_args = sigma * randn(height,width);
end
