function Y_Noncycle=noncycle(Y,CyclicNum,N_FFT)
%去前缀

%串并转换，直接把拖尾截掉了
[row_Y,column_Y]=size(Y);
%row_Y即为接收天线数
for i=1:row_Y
    Y_SP(:,:,i)=sp(Y(i,1:column_Y-rem(column_Y,(CyclicNum+N_FFT))),(CyclicNum+N_FFT));
end

%去前缀
[row,column,antenna_Rx]=size(Y_SP);
%column即是CyclicNum+N_FFT
for i=1:antenna_Rx
    for j=1:row
        [m1 m2]=size(Y_SP(j,:,i));
        if m2==CyclicNum+N_FFT
           Y_Noncycle(j,:,i)=Y_SP(j,[CyclicNum+1:CyclicNum+N_FFT],i);
