LFSR模块，单个模块，实现移位寄存器，生成测试用pattern

PLL是数字锁相环设计源程序, 其中, Fi是输入频率(接收数据), Fo(Q5)是本地输出频率. 目的是从输入数据中提取时钟信号(Q5), 其频率与数据速率一致, 时钟上升沿锁定在数据的上升和下降沿上；顶层文件是PLL.GDF-digital phase-locked loop PLL design source, in which Fi is the input frequency (receive data), Fo (Q5) is the local output frequency. Objective is to extract data input clock signal (Q5), its frequency and data rate line, the clock rising edge of the lock data the rising and falling edge; top-level document is PLL.GDF

A simple Manchester Encoder to convert serial data to Manchester encoded data.

这是基于Quartus2 开发环境和verilog hdl语言写的38译码器(This is based development environment and Quartus2 verilog hdl language used to write decoder 38)

说明：  RISC全部源码，包含仿真文件，使用makefile脚本编写，能通过vcs编译(RISC all source code, including simulation files, using makefile script, can be compiled through VCS)

实施软件定义无线电的关键第一步是向与数字到模拟控制器接口。好花费的时间是在这工作，因为驾驶 DAC 的信号的时间必须是正确的设备才能正常工作。Spartan3e 培训师局是有 LTC2624 DAC 连接到通过 SPI 总线 FPGA。用于进行通信的 DAC 的信号是 SPI_MOSI、 DAC_CS、 SPI_SCK、 DAC_CLR。下表中描述的接口信号。

qpsk调制解调，结果可以通过示波器进行观察(qpsk modulation and demodulation, the results can be observed by an oscilloscope)
