摘要
提出一种UHF频段OFDM移动多媒体传感器网络节点射频模块设计方案。它采用直接变频和功率回退技术,支持TDMA移动网络高速多路数据传输,具有较高的线性度、灵敏度、动态范围和带外抑制能力,可应用于要员车队监护、公安应急指挥和部队演习监视等系统。
A design of radio frequency (RF) module in ultra high frequency (UHF) orthogonal frequency division multiplexing (OFDM) node for mobile multimedia sensor network was presented. It adopts direct frequency conversion and power back-off technologies, supports high speed multiplex data transmission in time division multiple access (TDMA) mobile network, and has the ability of high linearity, high sensitivity, wide dynamic range and high out-of-band suppression. It can be applied to very important person (VIP) motorcade video wireless monitoring system, public security emergency command system, and battlefield surveillance system, etc.
