A low-latency, parameter modulation-estimation feedback protocol for wide-band channels is introduced for both pure line-of-sight and more general fading channels with several degrees of freedom. One round of the protocol consists of a data phase and a control phase and uses noncoherent detection. The asymptotic optimality in energy efficiency of the protocol is analyzed and an upper bound on the...
Software Defined Radio platforms are a flexible and cost efficient solution to deal with the increasing number of today's wireless communication standards. One interesting use case can be found in the automotive industry where the IEEE 802.11p standard enables Car-to-Car and Car-to-Infrastructure communication. In the context of this paper we present a physical layer implementation of the 802.11p...
Accurate information regarding a cognitive radio user's location and environment can enhance the adaptive and spectral awareness capabilities of cognitive radio systems. In this paper, a single-path multiband Time-of-Arrival (TOA) positioning technique for cognitive radio is proposed and the performance evaluated using maximum-likelihood (ML) location estimation for a typical rural scenario where...
The work described in this paper proposes two Smart Hybrid-Automatic Repeat Request (SHARQ) schemes with incremental redundancy, that are developed for a dual-hop network of two relays implementing cooperative communication. In a dual-hop network consisting of multiple relays, one of the most challenging tasks is to determine an appropriate trade-off point between the end-to-end block-error rate (BLER)...
