Carrier assignment algorithms for OFDM-based multi-carrier wireless networks with channel adaptation
(2008)We study carrier assignment in a single-cell multiuser OFDM multi-carrier system so as to satisfy user rate requirements with minimal resources. Different users experience different quality in different carriers due to ... -
On the use of distributed directive antenna arrays in mobile OFDMA networks
(2011)Distributed Omni Antenna Systems (OASs) have been proposed to increase the capacity of Broadband Wireless Access (BWA) systems. We investigate the extension of such systems by employing distributed Directive Antenna Arrays ... -
Sub-Sampled Time Domain Sparse Information in Wired OFDM and STBC-OFDM Systems
(2022)A sub-sampling method developed for wired or wireless Orthogonal Frequency Division Multiplexing (OFDM) systems is presented. The proposed technique can be activated during the exchange of sparse data. The sub-sampling ... -
Video-aware relay selection in single-carrier and OFDM wireless systems
(2014)In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ... -
