基于FPGA的GFP（通用成帧协议）封装数据成帧的实现。-FPGA-based GFP (Generic Framing Protocol) encapsulated data Framing realized.

通过MATLAB对过采样sigma-delta调制器进行仿真的设计方案，采用多级级联结构，有效减少运算量和硬件开销。-By MATLAB on the over-sampling sigma-delta modulator design simulation, using multi-stage cascade structure, effectively reduce the computational complexity and hardware overhead.

随着密码分析技术的提高，新的数据加密标准AES取代了过时的DES。文章在阐述AES/RSA加密算法的基础上，分别给出了利用AES/RSA实现客户端/服务器端网络数据传输的加密流程。最后在比较AES算法和RSA算法基础上，将AES与RSA相结合提出一种新的数据加密方案。-analysis technology improvements, new data encryption standard AES replaced the outdated DES. The article described AES/RSA encryption algorithm on the basis of the difference is the use of AES/RSA achieve client/server network data encryption process. Finally in comparison AES and RSA algorithm, based on AES and RSA will be combined, a new data encryption program.

摘要本文介绍了一种用CPLD设计GPS数字通道相关器中C／A码产生嚣的方法，详细分析了设计原理并给出了相应的仿真结果．这种设计方法已在我们研制的GPS，GLONASS兼容机中得到实际应用。-Abstract This paper introduces a design using CPLD digital channel GPS correlator in the C/A code generated noise approach, a detailed analysis of design principles and the corresponding simulation results. This design method has been developed in our GPS, GLONASS compatible in practical application.
