This paper presents a comprehensive evaluation of three peak-to-average power ratio (PAPR) reduction techniques which were proposed for the inclusion in the DVB-NGH (Next Generation Handheld) standard. After a detailed description of the three techniques, a common evaluation framework is defined, and the three techniques are compared both in their PAPR reduction capability and in their end-to-end...
In this paper we propose the usage of Single Carrier Frequency Division Multiple Access (SC-FDMA) in the Broadband Satellite Return Channel. Notably, SC-FDMA is able to improve the physical layer spectral efficiency with respect to single carrier systems, which has been used so far in the Return Channel Satellite (RCS) standards. However, it requires a strict synchronization and it is also sensitive...
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 OFDM modulation is its vulnerability to synchronization...
