—It has recently been recognized that the wireless networks represent a fertile ground for devising communication modes based on network coding. A particularly suitable applicati...
Abstract— The primary disadvantage of orthogonal frequencydivision multiplexing (OFDM) is the high time-domain peak-toaverage power ratio (PAR) that severely limits the transmitt...
Abstract—In this paper we study optimal transmission strategies in wireless ad-hoc networks using directional antennas. Each node is capable of adjusting its transmission rate as...
Abstract— Space Division Multiple Access (SDMA) is a promising solution to improve the spectral efficiency of future mobile radio systems. However, finding the group of MSs tha...
— In this paper, the frequency domain (FD) SAGE (Space-Alternating Generalized Expectation-maximization) algorithm has been extended to the MIMO case in order to determine the an...
— We propose the novel concept of cooperation for deafness prevention in directional antenna ad hoc networks, along with a low-complexity multiuser detector specialised for these...
Abstract— Zero-padded OFDM (ZP-OFDM) systems have recently been adopted in certain wireless systems, such as the multiband-OFDM based WiMedia standard, instead of the more common...
