文摘This article studies the coarse flame synchronization of orthogonal frequency division multiplexing access-time division duplex (OFDMA-TDD) systems and proposes a new method to improve coarse frame synchronization performance. The new method utilizes the user equipment to user equipment (UE-UE) interference, which is usually considered as a specific challenge for time division duplex (TDD) and also as implicit frame boundary information to enhance coarse frame synchronization performance. Numerical results show the synchronization performance is imoroved bv the new method.
