1．利用RBF神经网络，解决异或问题： 1）异或问题本质上是一个二分类问题:输入为向量[x1,x2],输出是标量，取值限定为0或1.(1. Use RBF neural network to solve different or problems: 1) an xor problem is essentially a binary problem: the input is a vector [x1,x2], and the output is a scalar whose value is limited to 0 or 1.)

Farrow 滤波器设计经典文章，作者是：FM.Gardner，farrow滤波器设计的始祖，经典值得推荐！（两篇文章）(Farrow filter design classic article, the author is: FM.Gardner, farrow filter design ancestor, classic worth recommending! (Two articles))

16QAM调制的OFDM，在限幅作用下输入输出互信息的变化情况(Mutual information of 16QAM modulated OFDM, with various clipping )

进行信号积累时，有的信号存在多普勒频率，不利于累加。该程序可完成对信号多谱勒频率的补偿。(Signal accumulation, some signal Doppler frequency, is not conducive to the accumulation. The program can be complete compensation of the signal Doppler frequency.)

说明：  可以直接仿真各种模型下常用水声信道，包含Bellhop,Kraken等源代码(Simulating the basic underwater acoustic channel, including the code and theory of Bellhop, Kraken and so on.)

通过simulink仿真工具架构的SCPC通信系统，基本架构为卫星通信系统，包括PCM编译码器、调制器、成型滤波、变频器、低噪声功率放大器、各类天线、模拟自由空间损耗、模拟等效噪声温度、卷积编译码器(The basic architecture of SCPC communication system based on Simulink simulation tool is satellite communication system, including PCM compiler, modulator, shaping filter, frequency converter, low noise power amplifier, all kinds of antennas, analog free space loss, analog equivalent noise temperature, convolutional compiling code.)
