中文说明：这是利用BPSK的调制中使用的扩频码的代码做出与Simulink的matlab的并且它测试发射机之间的BER和接收该代码也可进行测试，如果我们改变从BPSK调制到QPSK，看到在每一种情况下的BER之间的差
English Description：
this is spread spectrum code used with modulation of BPSK this code made with simulink matlab and it test the BER between the transmitter and receiver this code can also be tested if we change the modulation from BPSK to QPSK and see the difference between BER in each case
