Penyegerakan menimbulkan cabaran utama dalam sistem jalur lebar ultra (UWB) disebabkan kitaran tugas isyarat rendah dalam UWB. Kajian ini membangunkan skim penyegerakan yang berkesan untuk penerima IR-UWB pembeza bingkai untuk meningkatkan kelajuan penyegerakan. Mekanisme carian selari yang dicadangkan mengurangkan kawasan carian bagi sempadan simbol kepada hanya satu tempoh bingkai. Selain itu, hanya satu elemen kelewatan diperlukan dalam setiap cawangan, memandangkan garis lengah bergelung kongsi (SLD) juga dicadangkan untuk mengurangkan kerumitan pelaksanaan mekanisme carian selari. Simulasi dan analisis prestasi menunjukkan bahawa skim yang dicadangkan mencapai ralat min kuasa dua yang lebih rendah dan kebarangkalian pengesanan yang lebih tinggi daripada alternatif lain.

Abstract: Synchronization poses a major challenge in ultra wideband (UWB) systems due to low signal duty cycles in UWB. This study develops an effective synchronization scheme for frame-differential IR-UWB receivers to improve the synchronization speed. The proposed parallel search mechanism reduces the search region of the symbol boundaries to only a single frame duration. Moreover, only one delay element is needed in each branch, since a shared looped delay-line (SLD) is also proposed to lower the implementation complexity of the parallel search mechanism. Simulations and performance analysis show that the proposed scheme achieves a lower mean square error and a higher probability of detection than other alternatives.
