用VC++6.0编写的USB通讯测试的程序，可以实现查找PC的USB外设，读取USB外设的设备描述符等功能。对USB通讯初学者有很大的帮助。(Written in VC++6.0 using USB communications test procedure, can be achieved to find PC' s USB peripherals, read the USB peripheral device descriptor functions. USB communication to the very helpful for beginners. )

本人本科的毕业设计,基于Serpent密码的回退N协议的数据传输,希望可供大家参考,谢谢诶！()

最近在做毕设，ldpc码的编解码实现，这个是verilog实现。(Recently completed the set up to do, ldpc code codec implementation, this is the Verilog implementation.)

利用数据板卡进行数据采集，利用半满的方式将模拟量转换成数字量(Data card for data acquisition, the use of half-full way to convert analog into digital)

语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制，同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。(The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a significant impact. In this paper, TD-SCDMA System AMR Adaptive speech coding mechanism, at the same time analysis of AMR in the generation of Digital Linear Prediction (ACELP) algorithm and the realization of the process. The program can be achieved in a TMS320C5510.)
