说明：  一个opc客户端开发包，可以快速开发基于opc的客户端程序，此开发包需要授权(a client development kits, can be rapidly developed based on the client Oligomeric Proanthocyanidins procedures, this development kits need to empower)

本程序是基于LABWINDOWS/CVI 的，主要是通过串口采集下位机信息，然后显示状态信息并通过串口发送命令字节。(The program is based on LABWINDOWS/CVI.It get message from RS232and display status,then send command by RS232.)

说明：  该文档提供ASK,BPSK,QPSK,4QAM,16QAM等多种调制格式的LMS时域均衡算法，最初结构由MathWorks提供。(This document provides LMS time domain equalization algorithms in ASK, BPSK, QPSK, 4QAM, 16QAM and other modulation formats. The original structure is provided by MathWorks.)

将ADC对输入端口电压的转换结果按转换数据和对应的模拟电压的形式通过串口发送到PC机屏幕上显示(The ADC input port voltage conversion results by converting data and the corresponding analog voltage sent to the PC via the serial port on the screen)

协作通信中译码转发方式DF协作方式实验仿真主程序。(DF collaborative experiment simulation main program)

该程序全面仿真了蜂窝小区，主要是信道分配、切换等(The program overall simulation of a honeycomb village, mainly is the channel allocation, switch, etc )

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 )

正交频分复用系统中信号的调制与解调，我们用傅里叶反变换和变换来实现(Orthogonal frequency division multiplexing system signal modulation and demodulation, and we use the inverse Fourier transform to achieve transform)

说明：  在实际的调谐解调电路中，采用的是非相干载波解调，本振信号与发射端的载波信号存在频率偏差和相位抖动，因而解调出来的模拟I、Q基带信号是带有载波误差的信号。这样的模拟基带信号即使采用定时准确的时钟进行取样判决，得到的数字信号也不是原来发射端的调制信号，误差的积累将导致抽样判决后的误码率增大，因此数字QPSK解调电路要对载波误差进行补偿，减少非相干载波解调带来的影响。(In the actual tuning and demodulating circuit, non-coherent carrier demodulation is adopted, and the frequency deviation and phase jitter of the local oscillator signal and the carrier signal of the transmitting end are present, and thus the demodulated analog I and Q baseband signals are signals with carrier error.)
