通过Jakes模拟器来生成瑞利信道,瑞利信道的生成(Rayleigh Channel Generation through Jakes Simulator)

用最小二乘支持向量机实现负荷预测功能，计算各个误差指标的值，并输出负荷预测对比曲线，误差曲线等(The load forecasting function is realized by least square support vector machines (LSSVM). The values of each error index are calculated, and the load forecast contrast curve and error curve are also obtained)

说明：  pm调制，该仿真有助于相位调制,这是模拟调制方面的知识(pm modulation, the simulation will help phase modulation, which is knowledge of analog modulation)

利用Matlab生成GPS C/A 码的基带信号。 （1）产生卫星PRN 号码为“5”的一组C/A 码； （2）循环生成25 页的导航数据，GPS 时间可填入一固定的已知数值； （3）生成C/A 码扩频信号，每个C/A 码码片给出4 个采样数据； （4）基带信号采用方波信号，电平为0 和1，占空比为50 ％，不加入噪声，进一步生成某个特定的中频信号。(Matlab generated using GPS C/A code base band signal. (1) generation of satellite PRN number is " 5" a set of C/A code (2) loop generates 25 of the navigation data, GPS time can fill a fixed known value (3) to generate C/A code spread spectrum signal, each C/A code chip gives the four sampling data (4) baseband signals using square wave signal, level 0 and 1, 50 duty cycle, not to join the noise generated further a specific frequency signal.)
