An Efficient Precoder Design for Multiuser MIMO Cognitive Radio Networks With Interference Constraints

An Efficient Precoder Design for Multiuser MIMO Cognitive Radio Networks With Interference Constraints Abstract: We consider a linear precoder design for an underlay cognitive radio multiple-input multiple-output (MIMO) broadcast channel, where the secondary system consisting of a secondary base station (BS) and a group of secondary users is allowed to share the same spectrum with […]


A Distributed Learning Automata Scheme for Spectrum Management in Self-Organized Cognitive Radio Network

A Distributed Learning Automata Scheme for Spectrum Management in Self-Organized Cognitive Radio Network Abstract: We propose a distributed Learning Automata (LA) for spectrum management problem in Cognitive Radio (CR) networks. The objective is to design intelligent Secondary Users (SUs) which can interact with the RF environment and learn from its different responses through the sensing. […]
