Joint transmission power control in transponded SATCOM systems
Xin Tian, Genshe Chen, Khanh Pham, Erik Blasch · 2016
This paper presents a novel approach for the uplink transmission power control for satellite communication (SATCOM) links that share a transponder's transmission power. The proposed approach provides explicit link margins (LM) for both uplinks and downlinks against losses from various sources that are uncertain in nature. The feature allows the proposed algorithm to work effectively with information from SATCOM radio frequency (RF) situation awareness to establish transponded SATCOM links that achieve desired Quality of Service (QoS) requirements. The algorithm is applicable for both traditional satellite communication systems and protected Frequency Hopping (FH) SATCOM systems with transparent transponders.
