cdma系统，发射机采用直接扩频序列后发射，接收机采用MMSE接收机(cdma systems, the transmitter after the launch of direct sequence spread spectrum receiver using MMSE Receiver)

MPSK QAM MASK MPSK信号载频估计matlab程序(matlab program of estimating Carrier Frequency of MPSK QAM MASK MPSK signal )

说明：  脉冲压缩的匹配滤波。目标距离分别为10米，30米和100米，对于未压缩的脉冲，三个回波信号混叠在一起，不能分辨，而经过脉冲压缩的脉冲信号则可通过匹配滤波收到3个回波信号(Matched filtering for pulse compression.Target distances are 10 metres, 30 metres and 100 metres, respectively. For uncompressed pulses,The three echo signals are overlapped and can not be distinguished. While pulse compression can distinguish three echo signals after matched filtering)

说明：  利用锁相环来实现MSK信号的定时同步，采用的是gardner算法(Using phase-locked loop to achieve timing synchronization of MSK signal, Gardner algorithm is adopted.)

说明：  标准接口1-5V转换成4-20mA程序，应用于标准传感器接入(Standard Interface 1-5V Converting 4-20mA Program for Standard Sensor Access)

QPSK using system generator

在matlab下，基于循环前缀的仿真验证源代码，比较详细(In matlab, the simulation based on cyclic prefix for the source code, more detailed)

Mamul for connecting 840D SL system by OPC

说明：  用matlab实现简单的bpsk系统，熟悉bpsk系统的特性(Implementing BPSK with MATLAB)

说明：  Labview OPC和欧姆龙PLC通讯(LabVIEW OPC and OMRON PLC communication)
