BPSK (Binary Phase Shift Keying) -二进制相移键控。BPSK使用了基准的正弦波和相位反转的波浪，使一方为0，另一方为1，从而可以同时传送接受2值(1比特)的信息。本程序采用simulink实现传输彩色照片。并求出了不同信噪比时的误码率以及原图和传输后的图片，以及两者差值-BPSK (Binary Phase Shift Keying)　 - Binary Phase Shift Keying. BPSK uses the reference sine wave and phase inversion of the wave, so that one party is 0, the other is 1, which can be transmitted at the same time accept 2 value (1 bit) information. The program uses simulink to achieve transmission of color photos. And find out the different SNR when the bit error rate and the original image and after the transmission of the picture, and the difference between the two
