signal=source(n,N); %生成二进制代码
transmittedSignal=askModu(signal,bitRate,fc,N);%调制后信号

end
function transmittedSignal=askModu(signal,bitRate,fc,N)%signal为输入信
号，bitrate为bit速率，fc调制信号频率，N
%signal=[0 0 1 0 1 1 0 1];
% bitRate=1000000;
t=linspace(0,1/bitRate,N);
c=sin(2*pi*t*fc);
transmittedSignal=[transmittedSignal,signal(i)*c];
