Investigation and Comparison of 3GPP and NYUSIM Channel Models for 5G Wireless Communications
Theodore S. Rappaport, Shu Sun, Mansoor Shafi
Channel models describe how wireless channel parameters behave in a given scenario, and help evaluate link- and system-level performance. A proper channel model should be able to f…
Coordinated Two-Tier Heterogeneous Cellular Networks with Leakage Based Beamforming
Harsh Tataria, Mansoor Shafi, Peter J. Smith +1
In this paper we demonstrate the rate gains achieved by two-tier heterogeneous cellular networks (HetNets) with varying degrees of coordination between macrocell and microcell base…
On the Convergence and Performance of MF Precoding in Distributed Massive MU-MIMO Systems
Peter J. Smith, Callum T. Neil, Mansoor Shafi +1
In this paper, we analyze both the rate of convergence and the performance of a matched-filter (MF) precoder in a massive multi-user (MU) multiple-input-multiple-output (MIMO) syst…
Deployment Issues for Massive MIMO Systems
Callum T. Neil, Mansoor Shafi, Peter J. Smith +1
In this paper we examine a number of deployment issues which arise from practical considerations in massive multiple-input-multiple-output (MIMO) systems. We show both spatial corr…
On the Impact of Antenna Topologies for Massive MIMO Systems
Callum T. Neil, Mansoor Shafi, Peter J. Smith +1
Approximate expressions for the spatial correlation of cylindrical and uniform rectangular arrays (URA) are derived using measured distributions of angles of departure (AOD) for bo…
On the Statistics of Cognitive Radio Capacity in Shadowing and Fast Fading Environments
Muhammad Fainan Hanif, Peter J. Smith, Mansoor Shafi
In this paper we consider the capacity of the cognitive radio channel in a fading environment under a "low interference regime". This capacity depends critically on a power loss pa…
