— In any conditions where DC and RF power are at a prime, such as in satellite systems, transmit amplifiers are operated close to the saturation region to maximize both output power and DC-to-RF efficiency, at the price of introducing non-negligible spectral regrowth and in-band distortion. In order to mitigate these effects, predistortion techniques can be(More)
In this paper, we investigate the applicability of the 3GPP Long Term Evolution standard to mobile satellite systems. In order to counteract the satellite specific propagation conditions, we propose a novel inter-TTI (transmission time interval) interleaving technique allowing to break the channel correlation in slowly time varying channels. The Inter-TTI(More)
One of the key factors for the successful deployment of mobile satellite systems in 4G networks is the maximization of the technology commonalities with the terrestrial systems. An effective way of achieving this objective consists in considering the terrestrial radio interface as the baseline for the satellite radio interface. Since the 3GPP Long Term(More)
SUMMARY The paper considers the application of Orthogonal Frequency Division Multiplexing (OFDM) techniques in the physical layer of a satellite system devoted to the provision of digital multimedia broadcasting (DMB) services, which are presently the focus of extensive research and development endeavours. In particular, the paper demonstrates that the(More)
— The paper considers the comparison of Orthogonal Frequency Division Multiplexing (OFDM) and High Speed Downlink Packet Access (HSDPA) techniques in the physical layer of a satellite system devoted to the provision of digital multimedia broadcasting (DMB) services. In particular, the paper demonstrates that the inherently high spectrum efficiency of OFDM(More)
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(More)
