The Research of Massive MIMO is an emerging area, since the more antennas the transmitters or receivers equipped with, the higher spectral efficiency and link reliability the system can provide. Due to the limited feedback channel, precoding and code

Reliability is an important issue for emergency message broadcast services in vehicular Ad Hoc network （VANET）. Most investigations of such broadcast in VANET focus on multi-hop connectivity, taking all one-hop links for granted. But potential em

We propose a novel algorithm to optimize the energy efficiency (EE) of OFDM-based cognitive opportunistic relaying links (CORL) under secondary users (SUs) incorrectly sensing the unlicensed spectrum. We formulate an optimization problem with imperfe

The explosive growth of user traffic brings a great pressure on evolved packet core (EPC) caused by huge numbers of emerging mobile intelligent applications. An EPC with good flexibility and scalability is required. In this paper, we proposed a virtu

A novel energy efficiency (EE)-oriented cognitive spectrum sharing scheme in heterogeneous cognitive radio networks, called energy-efficient cognitive cooperation (ECC) is proposed, in which the primary system release a part of its radio spectrum to
