自己写的求解波松方程的matlab程序 并采用两种方法求解 (Writing their own to solve Poisson equation matlab program and the use of two methods for solving)

在预警系统中的定位时，需要将干扰信号读取出来，此程序就是对得到的二进制干扰信号进行读取并查看其图形。(Read binary interference signals.)

matlab时频分析配套源码第4章的程序，请大家共享(Matlab time-frequency analysis supporting source code, Chapter 4, please share)

程序仿真了瑞利信道，分析和大量实测表明，多径效应使接收信号包络变化接近瑞利分布。在典型移动通信中，衰落深度达30dB左右，衰落速率约30~40次/秒。(Rayleigh channel simulation procedures, analysis and extensive test shows that the received signal multipath effect changes in the envelope close to the Rayleigh distribution. In a typical mobile communication, fading depth of about 30dB, the decline rate of about 30 to 40 times/sec.)

读取信号，信号滤波，信号降噪，信号分帧，信号求时间差。(Read signal, signal filtering, signal noise, signal framing, find the time difference signal.)

说明：  粒子群算法优化支持向量机，优化过后很好用，准确率很明显(Particle swarm optimization for support vector machines)
