需要帮助使用PSKMOD

Question

M = 2; %Modulation order
imdata = imread('http://openvip.sourceforge.net/userdoc/lena_grayscale.jpg'); 
bdata = de2bi(imdata);        
sizec = size(bdata,1);         
sizer = size(bdata,2);         
nbits = sizec*sizer;            
msg = reshape(bdata,nbits,1);
txpsk = pskmod(msg,M);

上面的代码给出了以下错误。需要帮助修复以下错误

??? Error using ==> mtimes
Complex integer arithmetic is not supported.

Error in ==> pskmod at 101
y = exp(j*(theta + ini_phase));

Answer 1

只需将行msg = reshape(bdata,nbits,1)更改为msg = double(reshape(bdata,nbits,1));即可。它会工作。如果你需要更多澄清，请问我会解释你。
