qpsk调制 信道仿真 采用蒙特卡洛 信号和噪声随机生成，莱斯信道(qpsk modulation and channel simulation using Monte Carlo signal and noise randomly generated, Rice channel)

matlab实现一维小区定向信道锁定借用（BDCL）和FCA（固定信道分配）阻塞率比较的仿真程序，并对小区信道数对阻塞率的影响也进行了图形描述！(matlab plot to achieve one-dimensional directional channel locking to use (BDCL) and FCA (fixed channel allocation) Comparison of blocking rates of the simulation program, and the cell number of channels on the blocking probability is also studied in the graphic description!)

采用直扩方式构造的CDMA系统，最后给出CDMA系统的误码率曲线(Constructed using DS-CDMA systems approach, and finally gives CDMA system bit error rate curve)

8FSK的调制信号的产生、理论误码率及实际误码率统计分析(8FSK modulation signal s theoretical and actual BER analysis)

各种数字调制信号的产生，包括QAM,FSK,PSK,MATLAB程序(All kinds of digital modulation signal generation, including QAM, FSK, PSK, MATLAB program)

说明：  C++的简单例子，让你对C++有个基本的了解。(A simple example of C++, C++ so you have a basic understanding.)

2017年0616，该频域分解（FDD）土木工程中的一个输出系统识别技术的流行，特别是在结构健康监测。作为一个输出的算法，它是有用的当输入数据是未知的。FDD是模态分析技术，生成系统的实现采用了频率响应（多）输出数据参考。所附的MATLAB代码实现了这一技术的模态参数识别。为了使用此代码，处理（趋势、过滤等）时间的历史数据必须存储在一个Excel文件（数据每一频道栏目）。检查“加速度。对于时间的历史文件的一个实例xlsx”。(In 2017, 0616, frequency domain decomposition (FDD), an output system in civil engineering, was popular in identification technology, especially in structural health monitoring. As an output of the algorithm, it is useful when the input data is unknown. FDD is a modal analysis technique, and the implementation of the system adopts a frequency response (multiple) output data reference.)
