On the Physical Layer for Satellite Multicasting/broadcasting Services
نویسندگان
چکیده
In this paper the forward link performance of a satellite based UMTS system designed for the delivery of multimedia broadcast multicast services is investigated for different physical layer parameter combinations in AWGN, Rice and multipath radio channels. Guidelines for the choice of these parameters are given as a trade-off between bit error rate and processing delay. Also, the effects of nonlinearities, higher order modulations, and layered coding are investigated.

This paper presents a mechanism for dynamic rate control of satellite integrated services, based on a cross-layer approach, utilising link quality feedback from the satellite terminals. The mechanism, namely, satellite resource management system (SRMS) relies on the adaptive coding and modulation (ACM) capabilities of DVB-S2 in order to perform real-time adjustments on the physical, network and...
