Effect of Adaptive Threshold on Time Synchronization Based on PN Sequences in OFDM System

Abstract

In this paper, the time synchronization algorithm for orthogonal frequency division multiplexing (OFDM) system is analyzed. Based on the algorithm using PN sequence, different methods of setting adaptive detection threshold have been proposed before. We analyze the performance of the methods theoretically, and propose a method which is suitable for large… (More)
