A timing synchronization scheme in coordinated base-stations cooperative communications

Timing synchronization problem in Coordinated Multi-Point (CoMP) that results from time difference of arrival of users´ signals at cooperating base stations is one of the challenges that limits the application of these joint signal processing techniques to scenarios where the inter-site distances between base stations are small. In this paper, we propose a scheme that can solve this problem and can be applied in any scenario. The proposed method is compared to the normal CoMP operation. Simulation results indicate that the proposed scheme is viable to address the timing synchronization problem in CoMP operation.
