说明：  pi/4-dqpsk,可实现FPGA与电脑自发自收(pi/4-dqpsk,It can realize the self receiving of computer and FPGA)

PuTTY是一个Telnet、SSH、rlogin、纯TCP以及串行接口连接软件。较早的版本仅支持Windows平台，在最近的版本中开始支持各类Unix平台，并打算移植至Mac OS X上。除了官方版本外，有许多第三方的团体或个人将PuTTY移植到其他平台上，像是以Symbian为基础的移动电话。PuTTY为一开放源代码软件，主要由Simon Tatham维护，使用MIT licence授权。随着Linux在服务器端应用的普及，Linux系统管理越来越依赖于远程。在各种远程登录工具中，Putty是出色的工具之一。Putty是一个免费的、Windows x86平台下的Telnet、SSH和rlogin客户端，但是功能丝毫不逊色于商业的Telnet类工具。目前最新的版本为 0.68 latest release(PuTTY is a Telnet, SSH, rlogin, pure TCP, and serial interface connection software. The earlier version supported only the Windows platform, and in recent versions began to support various Unix platforms and was intended to be ported to Mac OS X. In addition to the official version, there are many third party groups or individuals that migrate PuTTY to other platforms, such as Symbian based mobile phones. PuTTY is an open source software that is maintained primarily by Simon Tatham and licensed using the MIT licence. With the popularity of Linux applications on the server side, Linux system management is becoming more and more dependent on remote. Putty is an excellent tool for various remote login tools. Putty is a free, Telnet, SSH, Telnet, and rlogin client on the Windows X86 platform, but it is no less functional than the business class tools. The latest version is 0.68 latest release)

说明：  数字信号处理，设计数字滤波器，利用MATLAB语言仿真实现(Digital Signal Processing, Design of Digital Filter and Realization by MATLAB Simulation)

说明：  qpsk基带调制和解调matlab程序，包括gardner位同步(qpsk modulate and demodulate in baseband use matlab code,including gardner time synchronization)

基于卷积编码的BPSK、OQPSK调制通信系统的仿真设计，较为简单(OQPSK Modulation Communication System Based on Convolutional Coding)

用于LDPC编码译码的仿真实现。包括随机生成校验矩阵、由校验矩阵产生生成矩阵、编码、加随机噪声、译码等内容。(For LDPC codec simulation. Including randomly generated check matrix, generated by the parity check matrix generator matrix, coding, plus random noise, such as decoding.)
