Program to implement convolution through VHDL

231卷积码的verilog实现，前面是详细的文档说明，有源程序，绝对原创！！！！(Verilog achieve 231 convolutional code, preceded by a detailed description of the document, the source, the absolute originality! ! ! !)

说明：  插值滤波器,用于音频解码调制解调,滤波器系数用移位相加实现(Interpolation filter, audio decoder for modulation and demodulation, filter coefficient shift combined with the realization of)

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.)

FPGA实现 DDS_讲的非常详细,师兄的一片论文-FPGA realize DDS_ talked about in great detail, of a senior thesis

说明：  采用vhdl语言编写的卷积编码（2.1.7），通过调试可直接下载使用(Convolution using vhdl language code (2.1.7) can be directly downloaded through the use of debugging)

decoder 2-4 digital core

说明：  uart 发送模块接收模块及tb，其中可以选择不同波特率进行收发，代码带有详细注释。(UART sending module and receiving module)

Material to learn how to use system verilog and how to write testbenches for verification.

通过verilog语言实现各种基本信号的调制解调过程，包括2psk,qpsk,ppm(Realize the modulation and demodulation process of various basic signals through verilog language, including 2psk, qpsk, ppm)

本章介绍了两个EDA技术的综合应用设计实例:数字闹钟和直接数字频率合成器DDS。-EDA chapter describes the two technologies integrated application design example: digital alarm clock and direct digital synthesizer DDS.
