无线电通信正交频移键控调制解调程序源码，给出输入数字信息序列，经调制后得到解调结果(QPSK for wireless electronic communication)

histogram matching for image enhancement

说明：  基于VMD的机车滚动轴承故障，实现故障信号的测量(Fault of locomotive rolling bearing based on VMD)

dc-dc converter，simulink(dc-dc converter using simulink)

此函数用于IS-95前向链路系统的仿真，包括扩频调制，匹配滤波，RAKE接收等相关通信模块。仿真环境: 加性高斯白噪声信道. (This function is used in IS-95 forward link system simulation, including the spread spectrum modulation, matched filter, RAKE receiver and other related communication module. Simulation environment: additive white Gaussian noise channel.)

卡尔曼滤波器介绍,北卡莱罗纳大学的,已经翻译成中文版了(Kalman filter, the University of North Kalailuona, has been translated into the Chinese version)

该程序用数值方法计算rayleigh-lamb波频散方程，得到频散曲线(the program is used to sovle the rayleigh-lamb equation by mumerical method,and the dispersion curve was plot)

单脉冲和差波束测角程序。 此程序实现了线阵8阵元的和差波束测角，利用全阵同时形成两个波束，形成和差波束，随着测量角度的增大其误差也逐渐增大，这是由于这种方法的近似所致和波束扫描时变胖(Single-pulse and beam deviation angle measuring procedures. This program implements linear 8-element array and differential beam angle measurement, using the whole array at the same time to form two beams, beam forming and poor, with the measurement of the angle increases the error also increases, which is a result of this approach approximate due to fat, and beam scan)

说明：  浮点数的定义及计算方法，可用于初级学习之用(floap contral)
