—In this paper, we present a novel joint symbol timing and carrier frequency synchronization algorithm for Orthogonal Frequency Division Multiplexing (OFDM) system with very low hardware complexity. Although we developed the proposed algorithm with reference to the DVB-SH standard, it is easily adaptable to other OFDM based systems. A well-known problem in(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)
— 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)
