Abstract :
This paper presents methods for synchronization In the downlink of a UMTS/TDD system. Space-time processing based on multiple receive antennas is used to suppress potentially strong co-channel interference caused by other base stations. We develop a detection-based synchronization procedure exploiting the structure of UMTS/TDD, and we present three alternative detection algorithms. Simulation results using various propagation scenarios indicate the good performance of our synchronization methods in the presence of strong co-channel interference.
