Abstract
In this paper, an efficient and robust simultaneous timing synchronization and channel estimation method for Cooperative MultiPoint Transmission and Reception (CoMP) is proposed. Efficiency is obtained by using the same two Orthogonal Frequency Division Multiplexing (OFDM) symbols for simultaneously transmitting preambles by all the base stations. Robustness is achieved by specially designed orthogonal sequences both in time and frequency domain. The proposed method is able to estimate the channels from several base stations without losing anything in performance with respect to the single transmission scenario. Furthermore, our proposed synchronization outperforms single transmitter methods and so, it could also be adapted for single base station OFDM systems.
