Coverage in multi-antenna two-tier networks
FREE-DOWNLOAD V Chandrasekhar, M Kountouris… – … , research Transactions on, 2009 Abstract—In two-tier networks – comprising a conventional cellular network overlaid with shorter range hotspots (eg femtocells, distributed antennas, or wired relays) – with universal frequency reuse, the near-far effect from cross-tier interference creates dead spots where reliable
Time-reversal detection using antenna arrays

We use a multi-static con- figuration with receive and transmit arrays of antennas. In time reversal, the backscattered field is recorded, time reversed, and retransmitted
Power allocation for a MIMO relay system with multiple-antenna users
FREE-DOWNLOAD Y Yu… – Signal Processing, research Transactions on, 2010 – Abstract—A power allocation or scheduling problem is studied for a multiuser multiple-input multiple-output (MIMO) wireless relay system where there is a non-regenerative relay between one access point and multiple users. Each node in the system is equipped with multiple
