Abstract :
Cellular OFDMA system is susceptive to inter-cell interference when a frequency reuse factor is one and all neighboring cells are fully loaded. At the cell edge, particularly, a severe synchronization error may occur due to decreased signal-to-interference ratio. In this paper, therefore, we propose a robust frame synchronization method in inter-cell interference for OFDMA systems. The proposed algorithm shows a clear peak at the correct frame timing and has low computational complexity
