modulate_high.m

此工程为为一个完整的bpsk

% 将已调信号调制到10倍的载波频率

function [ signal_out, xt ] = modulate_high( signal_in, fc, fs )
signal_temp = zeros(1,length(signal_in)*fc*fs);
signal_length = 1:length(signal_temp);
signal_temp(signal_length) = signal_in(floor((signal_length-1)/(fc*fs))+1);
xt = signal_length/fc/fs/8;
signal_out = signal_temp.*cos(2*pi*fc*xt);
