SampllingKinds
The following file contains three types of digital communications sampling. Contains ideal sampling, natural sampling and ZOH sampling, operate only for one single frequency signal, can be modified to add multiple signals with a base frequency. Greetings, I hope it helps.

(1)请推导出单径瑞利信道中的BPSK相干解调的理论误码率性能,并画出比特信噪比与误码率的关系曲线。
(2)在单径瑞利信道中,请设计一种时分的导引辅助的信道估计方法,用Simulink进行仿真,测量BPSK的误码率性能,画出比特信噪比与误码率的关系曲线,并与(1)的曲线进行对比。
((1) derived from single-Path Rayleigh channel coherent demodulation of BPSK theoretical bit error rate performance and draw-bit signal to noise ratio and bit error rate curve. (2) in a single Path Rayleigh channel, please design a guided night-assisted channel estimation methods, using Simulink simulation, surveying BPSK BER performance, drawn-bit signal to noise ratio and bit error rate curve, and with (1) comparing the curve.)

说明: 求解双层规划问题常用的算法有极点算法、直接搜索法、下降法和非数值优化方法(如模拟退火算法、遗传算法等),遗传算法的求解思路是:首先对上层的决策变量编码,代人下层规划模型,通过求解下层模型的决策变量值,代入上层模型计算适应度值,然后进行交叉、变异、选择操作,最后求出最优解。(Solving Bilevel Programming Problems with pole algorithm commonly used algorithms, direct search method, descent and non-numerical optimization methods (such as simulated annealing, genetic algorithms, etc.), genetic algorithm for solving approaches: the first on the top of the decision variable coding, on behalf of the were lower programming model, by solving the lower model of decision variables values into the upper model on behalf of the fitness value, and then crossover and mutation, select Options, and finally get the best solution.)
