说明：  该程序是在matlab中利用窗函数法设计滤波器的示例(The program is using the window function matlab filter design example)

How to combine MATLAB and xls

TRAINDIFFEVOL(NET,Pd,Tl,Ai,Q,TS,VV) takes these inputs, NET - Neural network. Pd - Delayed input vectors. Tl - Layer target vectors. Ai - Initial input delay conditions. Q - Batch size. TS - Time steps. VV - Either empty matrix [] or structure of validation vectors. and returns, NET - Trained network. TR - Training record of various values over each epoch: TR.epoch - Epoch number. TR.perf - Training performance. TR.vperf - Validation performance. TR.tperf - Test performance. TR.mu - Adaptive mu value.

上面传的算法主要是为了实现通过MUSIC算法进行DOA的估计，运行不存在问题(Pass above the algorithm is mainly in order to achieve by the MUSIC algorithm of DOA estimates, there is no problem running)

运用matlab实现霍夫曼编码，可以自己输入(Using MATLAB to achieve Hoffman encoding, you can input it yourself)

用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

带时延的纯方位角单站跟踪算法,它有效地解决了用EKF算法进行纯方位角跟踪时可能出现的不稳定和滤波发散现象以及声音信号的时延问题。(Pure time delay with a single station azimuth tracking algorithm, which effectively solved the EKF algorithm with pure azimuth tracking of the instability that may arise and filtering divergence phenomenon, as well as the voice signal delay problem.)
