it is about optimisation with swarm s method

一个OFDM 系统程序，产生的事2k DVB-T 信号，具体参数在程序中已经给出。(a ofdm system programe. DVB-T signal is produced. All description of parameters are given.)

包含了巴特沃斯滤波器的处理，属于数字信号处理的一部分(Includes the processing of the Butterworth filter, part of the digital signal processing)

电梯模拟问题，对电梯一次运行的停层次数进行模拟仿真。(Elevator simulation problem, the number of first run to the elevator stopped hierarchy simulation.)

遗传算法的实现，里面有详细代码的说明，关于选择交叉和变异(The implementation of genetic algorithm, there is a detailed code of instructions, about the selection of crossover and mutation)

本程序是用matlab编写的瞬时频率估计，供参考学习！(This program is written in matlab instantaneous frequency estimation for information to learn!)

说明：  利用matlab仿真软件，实现8QAM调制。在实现时采用正交调幅的方式,某星座点在I坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将2个调幅信号相加就是所需的调相信号。(Use of matlab simulation software to achieve 8QAM modulation. In achieving the adoption of quadrature amplitude modulation means of a constellation in the I coordinates of the projection to the modulation of the amplitude-phase carrier, in the Q coordinates of the projection to the range of carrier orthogonal modulation, and then the sum of two AM signals is the required phase modulation signal.)

FHSS-In this program, the detail about the Frequency Hopping is given. Noticing the fact that the spread spectrum is required for frequency hopping and is of concern

数字信号分析，用matlab你建立一个具有界面的频谱分析仪(make a FFT spectrum analyzer using the GUI of matlab and tells some basic knowledge of the spectrum analyze of a signal.)
