Anti-frequency-shift packet detection for D2D power-saving communications over Wi-Fi network
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...

| description | 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. |
