User-centric wireless access virtualization (WAV) allows each user to be served by a set of carefully selected transmission points (TP)s forming a user-specific virtual basestation (uVBS) adapted to its environment and quality of service (QoS) requirement. In this way, this new concept breaks away from the conventional cell-centric architecture to provide boundaryless communications in future 5G networks...
In this paper, we consider a collaborative beam-former (CB) design that achieves a dual-hop communication from a source to a receiver in highly-scattered environments, through a wireless network comprised of K independent terminals. The weights of the considered CB design at these terminals, derived to maximize the received signal-to-noise ratio (SNR) subject to constraint over the terminals' total...
In this paper, we consider a power-constrained signal-to-noise ratio (SNR)-optimal collaborative beamformer(OCB) design in highly-scattered environments. We show that its weights depend on non-local CSI (NLCSI), thereby hampering its implementation in a distributed fashion. Exploiting, the polychromatic (i.e., multi-ray) structure of scattered channels, we propose a novel distributed CB (DCB) design...
