Abstract:	摘要： A technique for timing-delay and frequency-offset estimations that takes advantage of a single dual-chirp preamble burst operating in frequency-non-selective fading environments is proposed. As the shape of the autocorrelation function of the dual-chirp signal does not essentially change by different values of frequency offset, the proposed technique provides a maximum-likelihood (ML) timing-delay estimation by exploiting only one pair of pseudo-noise matched filters (PN MFs), instead of conventionally exploiting a continuum of MFs, therefore approaching the Miller-Chang bound (MCB) in the timing-delay estimation with a channel gain and an initial phase error as nuisance parameters. Using the transform invariance property of the dual-chirp signal, the proposed technique estimates a frequency offset by exploiting frequency-domain PN MFs, therefore approaching the MCB in the frequency-offset estimation. The proposed technique accomplishes ML timing-delay and frequency-offset estimations to attain the performance bounds. The advantages of the proposed technique are verified by rigorous statistical analysis in conjunction with comprehensive computer simulations. 出版者： Stevenage: The Institution of Engineering and Technology 出版日期： 2013-04 出處： IET communications, 2013-04, Vol.7 (6), p.562-576 資源來源： Wiley Online Library Open Access 版權： The Institution of Engineering and Technology 版權： 2021 The Institution of Engineering and Technology 版權： Copyright The Institution of Engineering & Technology Apr 2013 識別號： ISSN: 1751-8628 識別號： EISSN: 1751-8636 識別號： DOI: 10.1049/iet-com.2012.0206
