Abstract :
This paper proposes a frame synchronization method for adaptive array antennas (AAA) in digital mobile communications, which can achieve excellent performance even in severe asynchronous co-channel interference environments, in contrast to the conventional correlator-based methods. The proposed scheme that is based on maximum a posteriori (MAP) estimation utilizes the AAA´s outputs of which interference signal components are drastically suppressed. Computer simulations show that the proposed scheme can operate properly even in interference-rich fading environments, and that it can significantly improve the synchronization performance
