bp网络训练后的测试，读取已经训练好的bp网络，进行实际应用(bp network training after the test, reading the training has been good bp network for practical application)

本人写的小程序，包含有QPSK、ASK、OOK、FSK、BPSK等几种调制方式(I wrote a small program, includes QPSK, ASK, OOK, FSK, BPSK modulation, such as several)

cohere(x,y,M) computes the coherence function using successive DFTs of length with a Hanning window and 50 overlap. (The window and overlap can be controlled via additional optional arguments.) We see a coherence peak at frequency cycles/sample, as expected, but there are also two rather large coherence samples on either side of the main peak. These are expected as well, since the true cross-spectrum for this case is a critically sampled Hanning window transform. (A window transform is critically sampled whenever the window length equals the DFT length.)
