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

Title:
Timing and Frequency Synchronization for Orthogonal Frequency Division Multiple Access Systems
Abstract:
Reliable timing and frequency synchronization is a major requirement in an OFDMA system as synchronization errors can result in inter-symbol-interference (ISI) and inter-carrier-interference (ICI) in the received signal, which severely degrade system performance. In this talk, data-aided timing and frequency synchronization techniques for downlink OFDMA transmissions will be presented. We will start with the conventional downlink transmission case, in which a user synchronizes to a base-station, followed by the coordinated multi-point transmission case, in which a user synchronizes with multiple base-stations at the same time. We will also present the results obtained from the test-bed, developed for the implementation of the proposed algorithms.
