二叉树定价模型是期权定价模型中最为简单也是最为实用的定价模型，其极限就是Black sholes定价模型的结果。(Binary tree pricing model is the most simple option pricing model is the most practical pricing model, the limit is Black sholes pricing model results.)

一直用途比较大的调制方式，高斯最小移频键控，在simulink中有比较大的参考价值(Has been the use of relatively large modulation, Gaussian Minimum Shift Keying reference value in simulink)

code is based on the satellite filter based technique dct compressioin

By evaluating its performance through computer simulations for various channels(it suitable for high-speed channel equalization.)

OFDM qpsk,16qam and 64 qam code

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)

In computer science, particle swarm optimization (PSO) is a computational method that optimizes a problem by iteratively trying to improve a candidate solution with regard to a given measure of quality.
