这是我们eda的课程大作业，用quartus仿真循环彩灯并下到板子里能完美的运行出四种波形。工程比较完整，希望对大家有帮助。

通过FPGA驱动千兆以太网口，完成SPARTAN6上的UDP数据包闭环测试，即通过网口发送数据包到FPGA，FPGA内部将接收到的数据返回到PC机，建议测试之前添加ARP静态绑定，FGPA内部的IP以及MAC地址在ROM里的COE文档里可以看到，发送端添加了CRC以及整体CHECKSUM的计算(Driven by FPGA Gigabit Ethernet port, UDP SPARTAN6 data packet on the closed loop test, through the network to send data packets to FPGA, FPGA will receive the data back to the PC, the proposed test before adding ARP static binding, FGPA internal IP and MAC address in the COE document in the ROM where you can see, the sender adds CRC and CHECKSUM integral calculation)

这是一篇现代通信原理课程的作业报告.题目为几种时频分析方法比较及应用.详细介绍了短时傅里叶变换、小波变换、魏格纳—威利分布和Cohen类时频分布这4种典型时频分析方法,并作了比较(This is a modern communication Principle operating report. Entitled Comparison of several time-frequency analysis and 应用. 详细 Jieshao the short time Fourier transform, wavelet transform, Wigner- Willie distribution and frequency distribution of Cohen Lei This four kinds of typical time-frequency analysis method, and compared)

Altera FIFO的多极级联，实现多个FIFO之间的数据传输。-Altera FIFO multi-polar cascading between multiple FIFO data transmission.

对信号实现2FSK调制,2FSK就是用数字信号去调制载波的频率（移频键控），是信息传输中使用得较早的一种调制方式。它的主要优点是：实现起来较容易；抗噪声与抗衰减的性能较好；在中低速数据传输中得到广泛的应用。-the performance of 2FSK based on verilog

基于FPGA的调制，实现了QPSK调制，所用芯片为Artera的CycloneIIEp2C5T114C8-FPGA-based modulation, realize the QPSK modulation, the chip used for Artera
