A degrees of freedom-optimal scheme for SISO X channel with synergistic alternating CSIT
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel are investigated. Three cases are considered for the availability of channel state information at the transmitters ... -
A discrete event simulation for the logistics of Hamad's container terminal of Qatar
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)A discrete even simulation is developed for the first container terminal of Hamad's new port of Qatar which is anticipated to start its operations by the end of 2016. The model is based on the operational knowledge of ... -
A hybrid TDMA-MAC cooperative relaying scheme: Stability and delay analysis
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)We consider a cooperative relaying system with any number of source terminals, one shared relay, and a common destination. We assume a slotted time division multiple access (TDMA) framework in which each source terminal ... -
Maximum Secondary Stable Throughput of a Cooperative Secondary Transmitter-Receiver Pair: Protocol Design and Stability Analysis
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, we investigate the impact of cooperation between a secondary transmitter-receiver pair and a primary transmitter on the maximum stable throughput of the primary-secondary network. Each transmitter, either ... -
MIMO vehicle to vehicle channels: An experimental study
( IEEE , 2014 , Conference Paper)In this paper, a platform for measuring the impulse response of wireless multiple-input-multiple-output (MIMO) vehicle-to-vehicle (V2V) channels is presented. The platform is developed using Rice University Wireless ... -
Novel cooperative policy for cognitive radio networks: Stability region and delay analysis
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)We consider a cognitive radio system that consists of primary user, secondary user, and their destinations. The secondary user has a relaying capability, i.e., it transmits the relayed packets from the primary user. Unlike ... -
On the coexistence of a primary user with an energy harvesting secondary user: A case of cognitive cooperation
( John Wiley and Sons Ltd , 2016 , Article)In this paper, we consider a cognitive scenario where an energy harvesting secondary user shares the spectrum with a primary user. The secondary source helps the primary source in delivering its undelivered packets during ... -
On the degrees of freedom region of the M x N Interference Channel
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, the K-user MIMO interference channel is considered. The asymmetric DoF region for the channel is studied. The asymmetric DoF represent the set of all achievable DoF combinations {d1, d2,..., dK}. For the ... -
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ... -
Transmit and receive cooperative cognition: Protocol design and stability analysis
( IEEE Computer Society , 2013 , Conference Paper)In this paper, we investigate the stability of a cooperative cognitive system. We propose a cooperative secondary transmitter-receiver system (CSTR), where, the secondary transmitter (ST) and the secondary receiver (SR) ...
