Sparsity-aware multiple relay selection in large multi-hop decode-and-forward relay networks
(
Springer International Publishing
, 2016 , Article)
In this paper, we propose and investigate two novel techniques to perform multiple relay selection in large multi-hop decode-and-forward relay networks. The two proposed techniques exploit sparse signal recovery theory to ...
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 ...
A sparsity-aware approach for NBI estimation and mitigation in large cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the coverage area. Therefore, in this ...
Sparsity-Aware multiple relay selection in large dual-hop decode-And-forward broadband relay networks
(
IEEE
, 2016 , Conference Paper)
In this paper, three novel techniques are proposed and investigated for multiple relay selection in dual hop OFDM networks. These techniques are based on the exploitation of sparse signal recovery theory and on carefully-designed ...
