这是一个完整的OFDM通信系统仿真代码。包括信源编码信源调制，信道编码，信道估计，峰均抑制比等。实际程序可用直接运行。(This is a complete OFDM communication system simulation code. Including the source modulation source coding, channel coding, channel estimation, peak to average ratio suppression. The actual procedure can be run directly.)

一个很不错的用时域有限差分法解决二维直角坐标系下正方格子的matlab程序(a very good use of the finite difference time domain method to solve two-dimensional Cartesian coordinate system is the square lattice procedures Matlab)

这个matlab代码仿真了M-QAM的传输。M的取值不同，调制方式分别为4QAM，16QAM，64QAM等。传输信道为AWGN信道，能出误码率曲线。(The matlab code simulation of the M-QAM transmission. The value of M, the modulation mode of 4QAM, 16QAM, 64QAM. The transmission channel is AWGN, the BER curves.)

说明：  使用Psim软件仿真，boost电路双闭环控制。(Using Psim software simulation, boost circuit double closed-loop control.)

曲线数据压缩是计算机图形学、计算机自动制图和地理信息系统( GIS) 等学科理论与方法研究的一个重要问题,其实质是一个信息压缩问题.RDP 算法是应用最为广泛的一种,由于容易编程实现且压缩结果较好, GIS 界许多著名商业软件公司(如Intergrap h ,ESRI ,LaserScan) 都把此算法作为其制图系统中一种曲线数据压缩的标准算法.(the well-known Ramer-Douglas-Peucker (RDP) algorithm for polyline data compression)

if a radio configuration is given, what are its anticipated capabilities (e.g., in terms of achievable data rate), taking into account recent information sensed, as well as the past experience and knowledge?”.Here learning schemes are considered for basic and extended based on neural networks and ANFIS are designed to enhance the learning capabilities of a cognitive terminal, in terms of assisting it to predict the data rate that a specific radio configuration could achieve if it was selected for operation.

说明：  PQ分解法计算潮流，短路计算，三机九节点模型(PQ decomposition method for power flow calculation)

this is useful for every one in simulation.
