文章详细介绍了TPC编码技术及信道容限， 是一篇不错的介绍TPC的文章-An important goal for a new communication system is to transfer information at a high rate while keeping energy consumption low. Shannon s channel capacity sets a limit on the tradeoff between the rate of infor

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) ra

ZigBee协议适应无线传感器的低花费、低能量、高容错性等的要求。Zigbee的基础是IEEE 802.15.4。但IEEE仅处理低级MAC层和物理层协议，因此Zigbee联盟扩展了IEEE，对其网络层协议和API进行了标准化。Zigbee是一种新兴的短距离、低速率的无线网络技术。主要用于近距离无线连接。它有自己的协议标准，在数千个微小的传感器之间相互协调实现通信。(The ZigBee protocol adapts to the requirements of low cost, low e
