CLEAR SKY DETERMINATION IN UPLINK POWER CONTROL USING DUAL TIME CONSTANTS

摘要

An uplink power control system and a machine-implemented method for determining clear sky and adjusting uplink power are provided. A receiving station, which may be a satellite terminal or a satellite gateway, receives a reference signal from a satellite. The reference signal may be sampled over a sampling time period in order to compute a filtered short-term average downlink SINR. A filtered long-term average downlink SINR may be adjusted toward the filtered short-term average downlink SINR using either a first time constant or second time constant, based on a relationship between the filtered long-term average downlink SINR and the filtered short-term average downlink SINR. In some implementations, the second time constant is less than the first time constant.
