Precoding is a promising multi-user multi-antenna transmission technique in satellite communication systems to meet increasing throughput demands and improve spectral efficiency. Various system and service configurations result in different precoder design methodologies.
Precoding has stood out as a promising multi-user multi-antenna transmission technique to meet the emerging throughput demand of satellite communication systems while awaiting the technological maturity for exploiting higher bands. Precoding enables the reduction of interference among co-channel beams while improving spectral efficiency. Satellite systems offer multitude of system and service configurations, resulting in different precoder design methodologies. This letter explores the motivation for the introduction of precoding, offers an insight to their theoretical development in diverse scenarios and presents some avenues for future development.
