Combination of closed-loop / open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. 一个第一通信站(50)从一个第二通信站(52)接收通信. A first communication station (50) receives a communication from a second communication station (...
In order to combat large scale shadowing and distance losses in a land mobile satellite system, an adaptive power control (APC) scheme is essential. Such a scheme, implemented on the uplink, ensures that all users' signals arrive at the base station with equal average power as they move wit...
