Optimization of probability of error in collaborative spectrum sensing of time-limited cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time resources in cognitive radio (CR) networks. The frame structures for sensing and data transmission, if the ...
Performance of eigenvalue based spectrum sensing in full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Spectrum sensing is a key component in any cognitive radio network. Recently full-duplex communication, i.e., the ability to transmit and receive at the same time at the same frequency, has become feasible. Residual self ...
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 ...
Underlay cognitive radio: What is the impact of carrier aggregation and relaying on throughput?
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate joint relay selection and optimal power allocation, as a means to maximize the achievable rate of an underlay cooperative cognitive radio with carrier aggregation, taking into account the ...
Protocol design and stability analysis of cooperative cognitive radio users
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
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 queue, whereas the cognitive user has three ...
