| 摘要 |
A method and system for controlling uplink power in a satellite communication system using error leveling is provided. The uplink power control system for a satellite communication system of a preferred embodiment of the present invention comprises a communication satellite (101) and at least one UET (105). The communication satellite (101) includes an error detector (211) and a comparator (215). The UET (105) includes a receiver (206) for receiving an error indicator signal from the comparator (215), and a power profile processor (216) for controlling the transmit power level of the particular chanslot being used by the UET in response to the error indicator. A preferred method for controlling the transmit power level of a particular chanslot assigned to a UET in a satellite communication system in accordance with the present invention includes determining an error count for an uplink data signal received from the UET in the chanslot (403), and comparing the error count to a predetermined error threshold (404). The method further includes generating an error indicator signal for the chanslot in response to the comparison (405), and controlling the transmit power level of the particular chanslot in response to the error indicator (409, 410).
