Advanced receiver design for gigabit satellite downlink transmission over the X-band

Abstract

In this paper, an advanced receiver design based on DVB-S2 standard is proposed for satellite downlink transmission over the X-band, which is capable of supporting over one Gbps high data rate transmission on a 375 MHz bandwidth without the need to tackle the rain fade effect. We illustrate its baseband design and implementation details including frame detection, timing and frequency synchronization, and phase recovery. Our fixed point based simulation results show that the proposed design is able to achieve promising performance under realistic frequency offset and phase noise setting.
