Timing Acquisition with Cooperation of Two Distributed Receive Antennas over Flat-Fading Channels
In the flat Rayleigh channels of linear cell,two distributed receive antennas are employed to receive the signal transmitted from the mobile station (MS) with a single antenna.We exploit the false alarm probability at the central processor to guarantee that the false alarm probability at each distributed antenna does not exceed the pre-defined probability of false alarm.Based on the exploited probability of false alarm at the central processor,a cooperative detection threshold of each antenna is derived for threshold detection.According to the threshold detection,a maximum-likelihood (ML)-based timing acquisition method is proposed for distributed antenna systems (DAS).Without increasing the pre-defined probability of false alarm,the analysis and simulation results show that the correct acquisition probability and the missed detection probability for each distributed antenna can be improved with the proposed method wherever the MS is located.
