MATLAB1

奥本海姆的《信号与系统》教材第二版中文版 适合初学信号与系统哦~(Oppenheim Signals and Systems " textbook second edition of the Chinese version suitable for beginners Signals and Systems oh)

基于随机减量法，求解结构的自由衰减曲线，稍作修改即可使用(Based on random decrement method, solving free vibration of curved, slightly modified to use)

基于多线程机制的，利用Matlab编写，粒子群优化算法。目标变量采用归一化处理，适用于所有的优化函数。优化函数自定义为fitness(x)。(Based on multi-threading mechanism, the use of Matlab to prepare, particle swarm optimization algorithm. Target variables using normalized treatment applies to all of the optimization function. Since the optimization function is defined as fitness (x).)

说明：  方阵进行信号方向检测的程序,不同阵源位置 (direction of arrival in quare array)

基于BP和GRNN神经网络的粮食产量预测研究，通过训练样本和测试样本的交叉验证，实现粮食产量预测效果的最佳化(Prediction of Grain Yield BP and GRNN based training through cross-validation and testing samples, to achieve the best effect of the Grain Production Forecast)

运用matlab的过程中的一些注意地方，为一个附件(Matlab course of the use of some of the attention of local, as an annex)

说明：  QPSK仿真OQPSK仿真，通信原理资料上面的 (QPSK)

蜂窝系统中分布蜂窝用户,蜂窝小区500米，随机分布的用户。(UE distribute)

锁相环的工作模式：单载波为“1”、BPSK调制为“2”、QPSK调制为“3” 对其进行仿真 修改可用于高动态(The PLL operating modes: single-carrier is "1", and the BPSK modulation is "2", the QPSK modulation is "3." Its simulation modifications can be used for high dynamic)
