In this paper, we focus our attention on the cooperative uplink transmissions of systems
beyond the LTE-Advanced initiative. We commence a unified treatment of the principle of …

This paper considers joint optimization of cooperative beamforming and relay assignment
for multi-user multi-relay wireless networks to maximize the minimum of the received signal …

This letter considers the secure MIMO transmission in a wireless environment, in which one
transmitter (Alice), one receiver (Bob) and one eavesdropper (Eve) are involved. Apart from …

Motivated by the work of Dahrouj and Yu in applying the Han-Kobayashi transmission
strategy for mitigating the intercell interference in a multi-cell multi-user multiple-input single …

For multisource single amplify-and-forward (AF) relay networks, the optimality of power
allocation is revisited from different solution aspect, and a universal optimization framework …

It is known that superposition signaling in Gaussian interference networks is capable of
improving the achievable rate region. However, the problem of maximizing the rate gain …

This paper is concerned with design problems of joint source power allocation and relay
beamforming in multi-user multi-relay networks that use single-carrier frequency division …

In this paper, we propose a novel single-group multicasting relay beamforming scheme. We
assume a source that transmits common messages via multiple amplify-and-forward relays …

This paper considers an underlay cognitive radio (CR) wireless network with the assistance
of a two‐hop decode‐and‐forward (DF) relay node. Different from the conventional CR relay …

Cognitive radio is a promising technique to solve the spectrum shortage problem in wireless
communications. Integrating wireless relaying into the cognitive radio networks can improve …
