说明：  使用ISE软件实现OFDM通信系统的框架搭建，完成上板前的仿真工作(Realization of OFDM communication system with ISE software)

spartan 3E和verilog HDL的初学者极好的教材，本程序可直接下载到spartan实验板上运行。(Spartan 3E and Verilog HDL beginners excellent materials, the program can be downloaded directly to the spartan experimental board run.)

数字锁相环 dpll的 编译通过,使用verilog HDL语言对锁相环进行基于FPGA的全数字系统设计,以及对其性能进行分析和计算机仿真的具体方法(Digital phase-locked loop dpll compiler through the use of verilog HDL language on the phase-locked loop FPGA-based digital system design, as well as its performance analysis and computer simulation of specific methods)

基于verilog的2FSK调制程序，simulink仿真通过(2FSK modulation program based on Verilog, Simulink simulation passed)

基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

VHDL的动态扫描显示六个数码管，包含分频代码产生25kHz的扫描信号作为时钟。(VHDL dynamic scanning display six digital tube contains 25kHz scanning signal is generated as a clock divider code.)

基于小波变换去噪，采用了vhdl编写，已经在和matlab上对比过，结果准确，而且大量的节约了时间，欢迎下载，可以在quartusii中查看RTL电路，可以在modesim中仿真出结果
