Kertas kerja ini adalah berkenaan dengan penyegerakan masa bagi isyarat UWB kadar tinggi yang beroperasi dalam persekitaran berbilang laluan yang padat, di mana akses mesti menangani gangguan antara bingkai (IFI), gangguan antara simbol (ISI) dan juga gangguan berbilang pengguna (MUI). Skim pemasaan bersama dan anggaran saluran berasaskan latihan dicadangkan, yang berdaya tahan terhadap IFI, ISI, MUI dan herotan nadi. Skim pengesanan kerumitan rendah yang serupa dengan skim rujukan penghantaran (TR) keluar sebagai produk sampingan. Untuk menyimpan simbol latihan, kami terus membangunkan skim terarah keputusan lanjutan (DD). Batasan yang lebih rendah pada kebarangkalian pengesanan yang betul diperolehi yang sesuai dengan hasil simulasi untuk nilai SNR sederhana hingga tinggi. Keputusan menunjukkan bahawa algoritma yang dicadangkan mencapai peningkatan prestasi yang ketara dari segi ralat min kuasa dua dan kadar ralat bit berbanding dengan algoritma "masa dengan templat kotor" (TDT).

Abstract: This paper is concerned with timing synchronization of high rates UWB signals operating in a dense multipath environment, where access must tackle inter-frame interference (IFI), inter-symbol interference (ISI) and even multi-user interference (MUI). A training-based joint timing and channel estimation scheme is proposed, which is resilient to IFI, ISI, MUI and pulse distortion. A low-complexity detection scheme similar to transmit-reference (TR) scheme comes out as a by-product. For saving the training symbols, we further develop an extended decision-directed (DD) scheme. A lower bound on the probability of correct detection is derived which agrees well with the simulated result for moderate to high SNR values. The results show that the proposed algorithm achieves a significant performance gain in terms of mean square error and bit error rate in comparison to the "timing with dirty templates" (TDT) algorithms.
