Abstract :
We propose a maximum a posteriori metric for the optimum detection of the primary synchronization channel of the UMTS/FDD mode. This metric is derived assuming a perfect knowledge of the small-scale propagation channel statistics at the mobile station. It is then extended to take into account time-switched transmit diversity at the base station. The performance of this optimum metric in terms of false detection rate is compared to that of the non-coherent averaging metric used in the evaluation process carried out by 3 GPP. The simulation results show a performance gain of up to 3 dB for critical indoor, outdoor-to-indoor and pedestrian propagation environments which are characterized by small time and multipath diversity.
