摘要: An open loop power control system for an orthogonal frequency division modulation (OFDM)-based fixed/mobile wireless system. A preferred and method comprise measuring signal strength of received interference-free pilot tones transmitted by a base station; determining pathloss according to level tones; controlling transmit the remote unit adjusting transmitting channel attenuation determined in preceding step. The may further monitoring at station uplink checking if is outside pre-set limits around target start each call; sending command mobile over broadcast increase or decrease level.
