method and arrangement for sendeleistungssteuerung in an uplink in a satellitenkommunikationsanordnung with high data rate and shipboard de - and remodulation
Disclosed are a method and system for controlling uplink power for signal transmission in a satellite communication system (10) employing on-board demodulation and remodulation and having a plurality of user terminals (11, 12) that are linked by and that communicate with each other by way of a satellite relay system (13). A downlink error rate of the data in a downlink data stream is determined based on known data bits. An end-to-end error rate of the uplink data stream and the downlink data stream is determined. An error rate of the signal transmission is then determined based on the downlink error rate and the end-to-end error rate. The signal transmission is then controlled based on the error rate of the signal transmission. IMAGE
