Joint bandwidth and power allocation in cognitive radio networks under fading channels
A problem of joint optimal bandwidth and power allocation in cognitive networks under fading channels is considered. It is assumed that multiple secondary users (SUs) share the sp...

Optimality of Diagonalization of Multicarrier Multi-Hop Linear Non-Regenerative MIMO Relays
Abstract—In this paper, a multicarrier multi-hop multipleinput multiple-output (MIMO) relay system is investigated. A linear non-regenerative strategy is applied at each relay no...
