Performance Analysis of Pre-detection and Post-detection Diversity reception schemes for Mobile Satellite Systems.
- Abstract
For mobile satellite systems, quality of service and service availability depend on the line-of-sight satellite availability. The satellite visibility is one of the major factors which influence satellite link availability, since the satellite channel behavior is depended on the link conditions between satellite and land user. Because of this, the mobile satellite systems are using satellite constellation in low elevation orbits, which can provide multiple satellite visibility. In this paper a closed form expression for the performance of the post-detection product detector combiner (PDC) operating on L correlated branches in Nakagami fading has been derived, considering the DPSK signaling scheme and Nakagami flat fading channel. The average bit error rate (BER) obtained with this scheme is compared to the ideal predetection maximum ratio combining (MRC), showing limited loss. The post-detection product detector combiner is shown to perform better than the selection diversity combiner (SDC) under the considered case of mobile satellite systems.
