神经网络的结构选4-5-3，学习速率为0.28，惯性系数为0.04，加权系数初始值取-0.5-0.5上的随机数。(4-5-3 neural network structure selection, the learning rate is 0.28, the inertia coefficient is 0.04, the initial value of weighting factor to take-0.5-0.5 the random number.)

simulink s函数，用C写的CRC校验和解校验的程序，原理简单，但是可以用来做学习simulink的好例子。(simulink s function, using C to write the CRC checksum checksum reconciliation procedures, the principle of simple, but can be used to make a good example of learning simulink.)

说明：  在抗干扰算法中，对抗干扰权加Chebyshev窗，以降低副瓣电平，使方向图更好(In the anti-jamming algorithm, Chebyshev window on the right and interference to reduce the sidelobe level, so that pattern better)

说明：  这是建立F16的非线性simulink模型，并且包含数据(This is the establishment of nonlinear simulink model F16, and includes data)

Matlab code for calculating orbital elements

这是一个非常重要的而又简单的程序，是书上常用和数学建模的好帮手( very good)

BCH(15,5,7)a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink. Simulate and draw its error performance with and without BCH coding, together with the theoretical no-coding curve, i.e. two BER-EbNo curves.(a communication system consists of binary source, 3 error-correcting BCH code of length 15 over GF(24) (i.e, BCH (15,5,7 code), the primitive polynomial is p(x)=1+x+x4), BPSK modulator, AWGN channel, coherent demodulator, decoder (either BMA or EA could be utilized to solve the error locator polynomial) and sink.
