摘要

提出了一种基于Wi-Fi接口的数据分组检测算法，它在OFDM符号同步定时度量函数中采用一种新型归一化因子作为分母，与传统方法相比，该算法不仅有较高的检测概率，而且阈值的设置无需预先估计频偏。理论分析和仿真结果表明，在AWGN信道中，提出的算法使数据分组检测阈值设置更为灵活。此外，在多径Rayleigh衰落信道下，阈值可以直接根据相应AWGN信道的情形进行设置。

Abstract

An efficient packet detection scheme based on Wi-Fi interface was proposed.It was implemented by employing a novel normalized factor as a denominator in OFDM symbol synchronization-timing metric.Compared to the old-tradition schemes

the proposed scheme can not only obtain great detection probability

but also achieve the threshold setting without pre-estimation of frequency offset.Both theoretical analysis and conducted simulation results show that the new scheme facilitates threshold selection for a wide range of signal-to-noise ratio (SNR) in additive white Gaussian noise (AWGN) channel.Besides

the threshold setting in multi-path Rayleigh fading channels can be determined according to the AWGN case straight forwardly.
