Interference-based optimal power-efficient access scheme for cognitive radio networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we propose a new optimization-based access strategy of multi-packet reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectrum. We devise an analytical model that ... -
Sparsity-aware narrowband interference mitigation and subcarriers selection in OFDM-based cognitive radio networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In this paper, the performance of an orthogonal frequency division multiplexing overlay cognitive radio network with subcarrier selection schemes is investigated. We propose three subcarrier selection techniques that reduce ...
