说明：  扩频通信系统下，直接扩频通信系统的仿真代码(Spread spectrum communication system, the simulation code of direct spread spectrum communication system.)

介绍了一种基于低成本CMOS摄像头的智能监控系统,实现了现场监控的实时化、智能化。系统可自动判别危险程度,可分别提供绿色、黄色和红色报警信息,并驱动相关附属设备工作。针对图像传输过程中的噪声,系统采用了对噪声图像使用局部算子的滤波技术来提高图像质量。根据对静态图像进行三原色分离后误差域的研究,达到背景与图像分离的目的,成功实现了图像的获取和处理。在低成本投入下,以简单的配置和简便的操作达到了高性能监控系统的功能。(Introduce a low-cost CMOS camera-based intelligent monitoring system, realize the scene in real-time monitoring and intelligent. The system can automatically determine the degree of risk, they can provide green, yellow and red alarm information, and drive the work-related ancillary equipment. For image transmission in the process of noise, system noise images of the use of local filtering operator technology to improve image quality. Based on static images RGB domain after the separation error research, background and images to achieve the purpose of separation, the successful implementation of the image acquisition and processing. Input in the low-cost, simple configuration and easy to operate to achieve a high-performance monitoring system.)

说明：  提供了三套ZigBee兼容的 平台，为我们的客户提供一种 只需要添加应用的解决方案。 所有的三种解决方案都是建立 在CC2420/CC2520上，而且 有很好的共存性。这些兼容的 平台缩短了产品进入市场的时 间，简化了系统设计和ZigBee 终端产品的验证。(Provided three sets of ZigBee-compliant platform, to offer our customers only need to add the application of a solution. All three solutions are built on CC2420/CC2520, but also the co-existence of good. These platform compatible product to shorten time-to-market and simplifies the system design and test ZigBee end-products.)

AES（The Advanced Encryption Standard）是美国国家标准与技术研究所用于加密电子数据的规范。它被预期能成为人们公认的加密包括金融、电信和政府数字信息的方法。本文展示了AES的概貌并解析了它使用的算法。包括一个完整的C#实现和加密.NET数据的举例。在读完本文后你将能用AES加密、测试 基于AES的软件并能在你的系统中使用AES加密。 　(AES (The Advanced Encryption Standard) is the National Institute of Standards and Technology for electronic data encryption standards. It was expected to be recognized by encryption including financial, telecommunications and government of digital information. This paper showed a picture of AES and its use of analytic algorithm. Including a complete C# and encryption.NET data, for example. After reading this you will be able to use AES encryption, AES-based testing and software in your system to use AES encryption.)
