对文本文件和音频文件进行OFDM调制和16QAM调制的matlab仿真。

function y = pol2bin(x)

% pol2bin
% 
% Converts polar numbers (-1,1) to binary numbers (0,1)
% Accepts a 1-D array of polar numbers
% Removes trailing zeros, since they are not valid data

% % Remove zeros - not needed with intelligent decoding
% last_data=length(x);
% while x(last_data) == 0
% 	last_data = last_data - 1;
% end

for i = 1:length(x)
	if x(i) == -1
		y(i) = 0;
