Opportunistic user access scheduling enhances the capacity of wireless networks by exploiting the multi user diversity. When frame aggregation is used, opportunistic schemes are no...
—Cooperative relaying has been shown to provide diversity gains which can significantly improve the Packet Error Rate (PER) in wireless transmissions. In ad hoc wireless routing...

— This paper presents an analytical model for the analysis of Hybrid ARQ techniques on Discrete Time Markov Channels by means of Markov chains. The first contribution is an orig...
Single-frequency simulcast networks use two or more Radio Base Stations (RBS) to transmit simultaneously the same signal on the same radio channel over the service area. To ens...

Abstract— In this paper, collocated and distributed spacetime block codes (DSTBCs) which admit multi-group maximum likelihood (ML) decoding are studied. First the collocated case...
