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 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 ... -
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 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 ...
