Abstract

The concept of relay transmission is applied to Land Mobile Satellite (LMS) communication where a terrestrial relay node forwards information from the satellite to the mobile unit. Two hop Amplify and Forward (AF) and Decode and Forward (DF) cases are considered where source, relay and destination, all are equipped with multiple antennas, using Maximal Ratio Transmission (MRT)-Selection Combining (SC) diversity technique for the first hop and Maximal Ratio Combining (MRC) for the second hop. We present analysis of both AF and DF in terms of outage probability and Symbol Error Rate (SER) for which closed form expressions are derived and show that DF always outperforms AF. Results are illustrated through several examples in order to assess the impact of multiple antennas at the nodes and shadowing severity parameter m on the performance.
