matlab的GUI编程指导，对有需要做GUI界面的朋友可能会有帮助。(GUI programming in matlab guidance necessary to have friends to do GUI interface may be helpful.)

完成双正交信号的数字通信系统的蒙特卡罗仿真。分析其在加性高斯白噪声下误码率与信噪比之间的关系，绘出误码率-信噪比曲线图，并和理论曲线进行比较。(Complete pairs of orthogonal signals in Monte Carlo simulation of digital communication systems. Analysis of the additive white Gaussian noise bit error rate and signal to noise ratio under the relationship between the mapped BER- signal to noise ratio curve, and and the theoretical curves for comparison.)

利用PSO算法优化求解PID参数,已发表文章,效果很好(Use of PSO algorithm for solving PID parameters, has published an article very good)

Simulates a Multifractal Model of Asset Return using a multiplicative lognormal cascade (Simulates a Multifractal Model of Asset Return using a multiplicative lognormal cascade See the following papaer A Multifractal Model of Asset Returns by B Mandelbrot- 1997 The current implementation uses the generator for the fractional brownian motion from B.
