Paper Detail

Paper:	SPCOM-L4.3
Session:	MIMO Training Design and Capacity Issues
Time:	Wednesday, May 17, 14:40 - 15:00
Presentation:	Lecture
Topic:	Signal Processing for Communication: MIMO channel estimation and equalization
Title:	Training Design for Channel and CFO Estimation in MIMO Systems
Authors:	Mounir Ghogho, University of Leeds, United Kingdom; Ananthram Swami, Army Research Lab, United States
Abstract:	For MIMO systems operating over frequency-selective channels, we establish the Cramer-Rao Bound (CRB) for the CFO and channel parameters. We derive training sequences so that the resulting CRB on the CFO is independent of the channel. We show that these designs lead to simple implementation of the maximum likelihood estimators of the CFO and channel parameters. Simulation results illustrate the performance of the proposed designs.
