Wi-Fi设备间节能通信抗频偏数据分组检测
Anti-frequency-shift packet detection for D2D power-saving communications over Wi-Fi network
摘要
Abstract
An efficient packet detection scheme based on Wi-Fi interface was proposed. It was implemented by employ-ing 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 accord-ing to the AWGN case straight forwardly.关键词
