Achieving Autonomous Compressive Spectrum Sensing for Cognitive Radios
Jing Jiang, Hongjian Sun, David Baglee +1
Compressive sensing (CS) technologies present many advantages over other existing approaches for implementing wideband spectrum sensing in cognitive radios (CRs), such as reduced s…
Maximum Throughput of a Cooperative Energy Harvesting Cognitive Radio User
Ahmed El Shafie, Tamer Khattab, H. Vincent Poor
In this paper, we investigate the maximum throughput of a saturated rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU harvests energy packets (…
On the Design of Relay--Assisted Primary--Secondary Networks
Ahmed El Shafie, Tamer Khattab, Ahmed Sultan +1
The use of cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investig…
Protocol Design and Stability Analysis of Cooperative Cognitive Radio Users
Ahmed El Shafie, Tamer Khattab, H. Vincent Poor
A single cognitive radio transmitter--receiver pair shares the spectrum with two primary users communicating with their respective receivers. Each primary user has a local traffic…
Outage Probability and Outage-Based Robust Beamforming for MIMO Interference Channels with Imperfect Channel State Information
Juho Park, Youngchul Sung, Donggun Kim +1
In this paper, the outage probability and outage-based beam design for multiple-input multiple-output (MIMO) interference channels are considered. First, closed-form expressions fo…
