Abstract :
TD-SCDMA is the 3G mobile communication air interface specification released by International Telecommunication Union (ITU). As a TDD system, synchronization in TD-SCDMA is a key influence factor of Quality of Service (QoS). Considering that mobile communication systems work in the environment of serious interference, multipath propagation and Doppler effect, it is difficult to establish synchronization. In this paper, we propose a novel synchronization technique based on Kalman filter which can smooth most of the channel interference. The experimental results indicate that this technique can short the time taken during synchronization and improve QoS obviously.
