Performance Improvement using Beam Diversity Technique in GEO Satellite Communication System over Correlated Nakagami-m Fading Channels
In GEO satellite communication with multi-beam antenna coverage,the decline of uplink performance will appear when the earth terminal near to the junction area of beams coverage.A method to solve the problem by beam diversity technique is studiedIn This paper. After presenting a new generation method of Nakagami-m fading channel simulation model,we build up a system model for the analysis of multi-beam diversity.In This model,terminal position,beam gain and channel fading level are taken into account. A number of results of simulation show that using beam diversity reception technique can effectively improve uplink performance of GEO satellite communication.
