Performance Analysis of WCDMA System for LEO Satellite Channel
In a Low Earth Orbit (LEO) satellite mobile multimedia system, the multiple access scheme should be capable of supporting the necessary features that would facilitate the provision of multimedia services. Wideband Code Division Multiple Access (WCDMA) is an attractive multiple access scheme for mobile multimedia communications based on LEO satellites. In this paper, the performance of WCDMA sys...
متن کاملPerformance Analysis of LEO Satellite Networks
We present an analytical model for computing call blocking probabilities in a LEO satellite network that carries voice calls. Both satellite-fixed and earth-fixed constellations with inter-orbit links and hand-offs are considered. The model is analyzed approximately by decomposing it into sub-systems. Each sub-system is solved in isolation exactly using a Markov process, and the individual resu...
متن کاملPerformance Analysis of MAC Protocol for LEO Satellite Networks
Considering that weak channel collision detection ability, long propagation delay and heavy load in LEO satellite communications, a valid adaptive APRMA MAC protocol was proposed. Different access probability functions for different services were obtained and appropriate access probabilities for voice and data users were updated slot by slot based on the estimation of the voice traffic and the ...
متن کاملLeo Satellite Communication System Handover Technology and Channel Allocation Strategy
Satellite handover happens frequently in Low Earth Orbit (LEO) satellite network due to satellite’s high mobility. In this paper, we propose a novel call admission control scheme which utilizes both the geographical information and the distance between the new call’s position and the preparing handover user’s position in the previous plot beam to intelligently decide whether to block a new call...
متن کاملChannel Model and Throughput Analysis for LEO OFDM Satellite Communication System
Low earth orbit (LEO) satellite has the advantages of global coverage, low propagation delay and low path losses, etc. Combined with orthogonal frequency division multiplexing (OFDM) transmission, LEO satellite system can support very high capacity suitable for wideband multimedia traffic. This paper analyzes the channel model and throughput for LEO OFDM satellite communication system. First, s...
