这个程序为通信中的16QAM调制程序，可用于无线或有线通信系统的调制仿真之用。(The 16QAM modulation communication this program can be used for wireless or wired communication system modulation simulation purposes.)

matlab代码，利用Farrow结构设计分数延时滤波器，滤波器阶数和个数可分别进行设置，利用最大最小准则近似。(Matlab code, using Farrow structure design fractional delay filter, filter order and number can be set separately, using the maximum and minimum criterion approximation.)

用xilinx ISE软件实现串口调试的程序其中，包含FIFO的一个IP核用于缓存数据

Digital pre-distortion (DPD) is an advanced digital signal-processing technique that mitigates the effects of power amplifier (PA) nonlinearity in wireless transmitters. DPD plays a key role in providing efficient radio digital front-end (DFE) solutions for 3G/4G basestations and beyond. Modern FPGAs are a promising target platform for the implementation of flexible wireless DFE solutions, including DPD.

在quartusII环境下采用对编解码芯片HD6408和HD6409驱动的方式实现曼彻斯特编解码(Environment in quartusII codec chip used on the HD6408 and HD6409-driven way to achieve encoding and decoding of Manchester)

这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )

基于DE2开发板的VGA显示模块，仅供大家参考(DE2 development board based on the VGA display module, for your reference)

基于Basys2开发板实现VGA输出，PS/2键盘接入的贪吃蛇游戏，键盘上下左右控制方向，小键盘+键控制速度，小键盘回车开始游戏，空格暂停游戏。(Basys2 based development board to achieve VGA output, PS/2 keyboard access Snake game, up and down the keyboard to control the direction, speed control keypad+ key keypad Enter to start the game, pause the game space.)
