Distributed Massive MIMO Downlink
ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019The feasibility of adopting distributed massive multiple-input multiple-output (D-MMIMO) for mitigating the achievable rate loss incurred by spatially-correlated fading at space-constrained user antenna arrays when served by co-located massive MIMO (C-MMIMO) counterpart is investigated.

UWA massive MIMO communications
OCEANS 2015 - MTS/IEEE Washington, 2015Underwater acoustic (UWA) channels are characterized by low availability of bandwidth, large propagation delays and fast varying multipaths. The fast variation of multipaths, in particular, hampers the bandwidth efficiency of UWA channels, as a significant percentage of transmission resources should be allocated to pilots. The problem magnifies further

Demand for wireless throughput, both mobile and fixed, will always increase. One can anticipate that, in five or ten years, millions of augmented reality users in a large city will want to transmit and receive 3D personal high-definition video more or less continuously, say 100 megabits per second per user in each direction.
