Abstract

Abstract:

This article studies the coarse frame 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 improved by the new method.

Key words:

orthogonal frequency division multiplexing access;time division duplex;synchronization;training symbol
