16QAM 在AWGN信道中的BER表现(BER performance of 16QAM in AWGN channel)

OFDM系统中，部分传输序列PTS的算法源码((Orthogonal Frequency Division Multiplexing PTS)

说明：  用VHDL语言在CPLD/FPGA上实现浮点运算的方法(in VHDL CPLD/FPGA achieve floating-point computation methods)

短波信道watterson模型的建模仿真，已经编译通过。(Watterson HF channel modeling and simulation model has been compiled through.)

说明：  Mamul for connecting 840D SL system by OPC

这是16QAM的仿真，带GUI界面，很好用的。(This is 16QAM simulation, with GUI interface, very useful.)

ITRI CIM Emulator能够读取SML档案，主要功能是用来测试半导体设备的通讯功能，它支持SECS-I/SECS-II/HSMS-SS通讯协议，支持SML格式，具有强大易用的自动化测试功能，免安装即拷即用。 使用前需要先将RS232连接线接好运行软件，选择检视。在设定SECS-I对话窗口中输入相关的通讯参数。(ITRI CIM Emulator can read SML files. Its main function is to test the communication function of semiconductor devices. ITRI CIM Emulator supports SECS-I/SECS-II/HSMS-SS communication protocol, supports SML format, has powerful and easy-to-use automated testing function, and exempts installation and copy-and-play. Before you use it, you need to connect the RS232 connection line to the running software and select the view. Input the relevant communication parameters in the SECS-I dialog window.)

估计接收到的直扩信号的载频，码速率，以及扩频增益(Estimate the carrier frequency, code rate, and spread spectrum gain of the received DSS signals)

本程序通过分析OFDM信号的循环平稳特性，利用循环谱对OFDM信道进行估计。(This procedure by analyzing the OFDM signal is cyclostationary properties, the use of cyclic spectrum of the OFDM channel estimation.)

频率估计，是一种比较简单的算法，很基础，有助于初学者应用(Frequency estimation, is a relatively simple algorithm, it is based applications to help beginners )
