About this document
Estimating Time Dispersion in OFDM Systems by sunitkdsp is a document available to read on EtoBox.
This document proposes algorithms for estimating time dispersion (frequency selectivity) of wireless channels in adaptive OFDM systems. It discusses how knowledge of time dispersion can help optimize OFDM system design parameters like cyclic prefix length. It then presents three algorithms: 1) Estimating the power delay profile from frequency domain channel estimates, and extracting time dispersion parameters. 2) Using the magnitude of channel estimates to remove phase bias from synchronization errors. 3) U
