关于SPWM调制设计VHDL代码 关于SPWM调制设计VHDL代码(SPWM modulation on the design of VHDL code design on the VHDL code modulation SPWM)

本程序使用Verilog语言实现了SPI接口的设计，可以直接烧到FPGA实现与MCU的通信,自带有测试文件。(The program uses the Verilog language design SPI interface, you can burn directly communicate with the FPGA, MCU, comes with a test file.)

华为内部资料，关于FPGA设计的详细过程介绍，很不错的。本文档从FPGA器件结构出发以速度路径延时大小和面积资源占用率为主题描述在FPGA设计过程中应当注意的问题和可以采用的设计技巧。(Huawei internal information, with regard to detailed FPGA design process of introduction, it is good. This document from the FPGA device structure in order to speed the path delay and area the size of the theme of the occupancy rate of resource description in the FPGA design process should pay attention to the problems and design techniques can be used.)

说明：  串口操作源代码，本代码采用veilog hdl语言编写，并经过本人多次验证。(source code, the code used veilog HDL language, and after I repeatedly verified.)

Program for simulate a prtsc

手把手教你学FPGA 仿真篇,简单实用。(Hand in hand teach you to learn FPGA simulation, simple and practical.)

实现对LCD1602的Verilog HDL编程(the program for LCD1602 based on Verilog HDL)

Matlab code to simulation the wireless channel type.This is the most common case called Rayleigh channel.And in the frequency selective channel.

基于FPGA的直接序列扩频发射机的设计与仿真。实验中以QuartusII 7.2 为设计和仿真工具， 各模块采用Verilog HDL设计并封装，顶层使用图形设计方式,最后得到的仿真结果使用Matlab描点来绘制出波形。 (FPGA-based direct sequence spread spectrum transmitter of the design and simulation. Experiment to QuartusII 7.2 for the design and simulation tools, the module using Verilog HDL to design and package, the top-level use of graphic design, and finally the simulation results obtained using the Matlab description points to draw waveforms.)
