There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of the proposed research is to model the effect of beam alignment errors arising due to inaccurate channel estimation and analyze the impact on the system-level performance of a directional millimeter-wave (mm-wave) cellular network. Specifically, by modeling the variance of the beam alignment errors using the Cramer-Rao lower bound (CRLB) of angle-of-arrival (AoA) estimates and utilizing stochastic geometric techniques, this research aims to quantify the loss in the achievable signal-to-noise ratio (SNR) and rate coverage of the network. The overall research is divided into three phases: 1) Modeling and analysis of a mm-wave only network with single-user beamforming at the BS and an isotropic antenna at the user, 2) Extension to a multi-user (MU) multiple-input multiple-output (MIMO) scenario, and 3) Extension to a heterogeneous network consisting of sub-6 GHz and mm-wave BSs.
