摘要

Nowadays satellite communications are undergoing strong development in order to follow explosive increase in requirement for superior data rate, capacity and omnipresent connectivity. On the apex of that, satellite communication industry has to keep promptness with terrestrial communication technology, which has shown strong and fast development. In this view, Multiple Input Multiple Output (MIMO) technology is a promising candidate. Multiple Input Multiple Outputs along with multicarrier modulation technique can be a good solution to mitigate frequency selective fading. Single Carrier Frequency Division Multiple Access (SC-FDMA) has shown robustness to multipath fading and has got the same characteristics as that of (Orthogonal Frequency Division Multiplexing (OFDM). The main advantage of Single Carrier Frequency Division Multiple Access is that it has low Peak to Average Power Ratio (PAPR). Due to low Peak to Average Power Ratio, Single Carrier Frequency Division Multiple Access is used in uplink for Land Mobile Satellite (LMS) systems. The link level performance of Land Mobile Satellite systems is diminished by rapid amplitude variations of the received signal due to shadowing. In this paper we have investigated, Single Input Multiple Output (SIMO) Single Carrier Frequency Division Multiple Access performance for Maximal Ratio Combining (MRC) diversity over correlated shadowed Rice Land Mobile Satellite channel, where the Line Of Sight (LOS) follows Nakagami-m distribution.
