滤波器设计代码，很好有用希望大家能够用，多多交流(Filter design code, a good hope that we can be useful, and more exchanges)

simple code for data echo cancellation

简单函数优化的遗传算法程序，遗传算法从问题解的串集开始搜索，而不是从单个解开始。这是遗传算法与传统优化算法的极大区别。传统优化算法是从单个初始值迭代求最优解的；容易误入局部最优解。遗传算法从串集开始搜索，覆盖面大，利于全局择优。(A genetic algorithm program optimized by simple functions)

通过MATLAB编程，实现模拟退火算法的功能，一次实现TSP问题。(Through MATLAB programming, to achieve the function of simulated annealing algorithm, a TSP problem.)

这是一个完整的无线通信系统中物理层的仿真程序，通过扩频技术（直接序列扩频）让信号通过高斯，瑞利等信道进行信噪比分析，得出结论(This is a complete wireless communication systems in the physical layer of the simulation program, through the spread-spectrum techniques (Direct Sequence Spread Spectrum) to signal through the Gaussian, Rayleigh channel for signal to noise ratio, such as analysis, come to the conclusion)

Scholarship processing system is developed for a scholarship department of a college. The scholarship department handles the scholarships sanctioned by the government to various students of the colleges. It computerizes all the transactions of scholarship department like issuing of forms, submission of forms, and sanction college and distribution to the students. This project intends to reduce the heavy paper work, which is otherwise involved, in the manual system. Different types of reports are generated. At present the college maintains manual records, in the form of registers, files, etc. to store the scholarship details of the students. New scholarships to be issued, involves heavy paper work. It also leads to data redundancy. Student details are recorded in multiple files. To overcome all these we are developing this Scholarship Information System. To provides maximum number of service to the users. To reduce the errors and the paper work that occurs in the manual system.
