利用NPW模型实现雷电放电过程的路径模拟(Using NPW model to simulate the path simulation of lightning discharge process)

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.)

说明：  产生正弦信号时域波形及频谱，并通过希尔伯特滤波器。其中希尔伯特滤波器有两种产生方式，一是使用MATLAB自带的FDAtool；二是程序编写。(The time-domain waveform and spectrum of sinusoidal signal are generated and passed through Hilbert filter. There are two ways to generate Hilbert filter, one is to use FDAtool in MATLAB, the other is to write programs.)

说明：  网络芯片ch563读写u盘例程，例程完整，方便开发(The network chip ch563 reads and writes the U disk routine, which is complete and convenient for development)

C00-NTAH-20070827-008-LGE-PAPR Reduction for OFDM

说明：  通过MATLAB做一个用户登录的GUI页面，实现登录、注册等功能(Make a user login GUI page through MATLAB to realize login, registration and other functions.)

说明：  一个opc客户端开发包，可以快速开发基于opc的客户端程序，此开发包需要授权(a client development kits, can be rapidly developed based on the client Oligomeric Proanthocyanidins procedures, this development kits need to empower)

说明：  7. 单径瑞利信道中的两发一收STBC： (1) 分析误码率的理论性能，画出比特信噪比与误码率的关系曲线。 (2) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。(7. Two outgoing and one outgoing STBC in single-path Rayleigh channel: (1) analyze the theoretical performance of bit error rate and draw the curve of the relationship between bit SNR and bit error rate. (2) please design a specific navigation-assisted channel estimation method, Simulink simulation, measurement of BPSK modulation error rate performance.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn.)
