SIMO Diversity with Antenna Selection for DVB-S2/RCS in LMS Scenarios

In this paper, we propose a Single-Input Multiple- Output (SIMO) diversity technique to improve the link reliability of a satellite communications system. In particular, the DVB-S2 communication system is investigated in a land mobile satellite environment. Realistic physical layer simulations are carried out to better evaluate the possible gain of using multiple receiving antennas at the receiver side. A hybrid selection technique of the available antennas is presented to reduce the complexity and the cost of the user terminal.
