Low resolution (LR) is an important issue when handling real world face recognition
problems. The performance of traditional recognition algorithms will drop drastically due to …

With the fast development of highspeed railways, a call for fulfilling the notion of
communication at “anytime, anywhere” for high-speed train passengers in the Train …

Maximisation of the sum‐rate of secondary users (SUs), equipped with multi‐antenna
transmitters and receivers, is considered in the context of multi‐input–multi‐output antenna …

We consider a MIMO-OFDM-based cooperative cognitive radio network (CCRN) in which
there exists a number of regenerative relays to cooperate with the cognitive base station …

The optimal resource allocation in MIMO cognitive radio networks with heterogeneous
secondary users, centralized and distributed users, is investigated in this work. The core aim …

A multiple‒input multiple‒output orthogonal frequency division multiplexing based
cooperative cognitive radio network is considered in this study, where the cooperation …

The optimal resource allocation in multi‐antenna multi‐band cognitive radio networks with
heterogeneous secondary users (SUs) and underlay strategy is presented in this work. The …

In this paper, the game theory approaches are used to solve the power schedule problem in
the wireless communication network. All sensors can be affected by DoS attackers when …

The authors consider the resource allocation issue in multiple‐input multiple‐output‐
orthogonal frequency division multiplexing‐based cooperative cognitive radio networks with …

The core aim of this work is the maximization of the achievable data rate of the secondary
user pairs (SU pairs), while ensuring the QoS of primary users (PUs). All users are assumed …
