摘要

针对采用正交频分复用(OFDM)的高数据速率无线局域网系统，提出了一种前置信号短的突发同步方案。该方案由自动频率控制(AFC)和符号定时检测组成，使我们能够将前言长度缩短到传统前言长度的1/4。计算机仿真结果表明，在选择性瑞利衰落信道中，该同步方案对所需E/sub / b//N/sub 0/的衰减小于1 dB。

A fast burst synchronization scheme for OFDM

This paper proposes a burst synchronization scheme with a short preamble signal for high data rate wireless LAN systems that use orthogonal frequency division multiplexing (OFDM). The proposed scheme, which consists of automatic frequency control (AFC) and symbol timing detection, enables us to shorten the preamble length to 1/4 that of a conventional one. Computer simulation results show that the degradation in required E/sub b//N/sub 0/ due to the synchronization scheme is less than 1 dB in a selective Rayleigh fading channel.
