A Low-Overhead Frame Structure Design for Short Frame Burst OFDM

Abstract

In short frame burst orthogonal frequency division multiplexing (OFDM) communication system, time resource is very essential. In this paper, we propose a scheme to reduce the frame overhead. Both the guard sequence and the preamble sequence are used for automatic gain control (AGC) adjustment to shorten the total frame length. The proposed frame structure design can increase the average data transmission rate by 14% at most. In addition, we compare the performance of the proposed frame structure and the traditional frame structure in timing synchronization and frequency offset estimation according to the simulation results, and prove the feasibility and effectiveness of this scheme.
