说明：  高阶累积量进行识别常用的数字调制信号，低信噪比下识别率高达90%(It uses the method of high cumulant to recognize usual digital signals, under low SNR, the radio is still over 90%.)

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.)

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.

说明：  cdma的码同步实现，使用matlab实现(Code synchronization of CDMA)

OPNET仿真程序。LEACH算法在传感器网络中的实现。OPNET在无线传感器网络中的实现程序还是比较少见的。(OPNET simulation program. LEACH algorithm in sensor networks. OPNET implementation of procedures in wireless sensor networks is still relatively rare.)
