Achievable Rates of Buffer-Aided Full-Duplex Gaussian Relay Channels
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output Gaussian relay channel. The FD relay still suffers from residual self-interference (RSI) after ... -
An efficient reduced complexity PAPR reduction approach for 3GPP LTE system
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In wideband communication systems, Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has been proposed as an efficient technique to enhance the link reliability and the spectral efficiency. ... -
Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
( Elsevier , 2013 , Article)In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ... -
Degrees of Freedom of the Full-Duplex Asymmetric MIMO Three-Way Channel with Unicast and Broadcast Messages
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)In this paper, we characterize the total degrees of freedom (DoFs) of the full-duplex asymmetric multiple-input multiple- output (MIMO) three-way channel. Each node has a separate-antenna full-duplex MIMO transceiver with ... -
Design and Analysis of Sparsifying Dictionaries for FIR MIMO Equalizers
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)In this paper, we propose a general framework that transforms the problems of designing sparse finite-impulse-response linear equalizers and nonlinear decision-feedback equalizers, for multiple antenna systems, into the ... -
Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO OFDM transceivers
( IEEE , 2012 , Conference Paper)In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ... -
Energy efficient antenna selection for a MIMO relay using RF energy harvesting
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Energy harvesting has emerged as a promising technique which helps to increase the sustainability of wireless networks. In this paper, we consider a network with a single source, single destination and a single relay ... -
Energy Efficient Antenna Selection for a MIMO Relay Using RF Energy Harvesting
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Due to rapid growth in traffic demands and the number of subscribers, the transmit energy consumption becomes critical, both environmentally and economically. Increasing energy efficiency for wireless networks is the main ... -
Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
( IEEE , 2011 , Conference Paper)The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ... -
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
( IEEE , 2013 , Article)In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ... -
Maximum likelihood detection of precoded SFBC in frequency-selective fading channels
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)In this paper, we derive the maximum likeli-hood detector (MLD) for precoded space-frequency block coded (SFBC) systems where orthogonal frequency divi-sion multiplexing (OFDM) is incorporated. The obtained results reveal ... -
