Cet article présente une structure de détection de paquets haute performance et efficace sur le plan matériel, qui utilise un corrélateur croisé pour le M- une opération de corrélation temporisée d'échantillonnage et un calculateur de puissance de signal utilisant les échantillons d'entrée reçus inférieurs ou égaux à un suffixe de longueur complété par des zéros M. Nous étudions les caractéristiques détaillées du détecteur de paquets proposé. Dans cet article, les performances d'une classe d'algorithmes de détection de paquets dans les environnements de canaux ultra-large bande (UWB) sont également étudiées. Le meilleur algorithme de détection de paquets pour la transmission UWB à multiplexage par répartition orthogonale de la fréquence multibande (MB-OFDM) est déterminé par une analyse et des simulations approfondies. Les résultats de l'analyse montrent que la structure de détection de paquets proposée présente des avantages en termes de complexité matérielle ainsi que de performances par rapport aux structures de détection de paquets existantes. Afin d'effectuer efficacement la détection de paquets avant le mode de contrôle automatique de gain (AGC), nous étudions les effets à la fois d'un décalage de fréquence et du niveau de gain initial d'un amplificateur à gain variable (VGA) sur les performances de détection de paquets. Nous suggérons également une technique de contrôle de gain VGA pour améliorer les performances de détection des paquets.

Abstract: This paper presents a high performance and hardware efficient packet detection structure, which employs a cross correlator for the M-sample time delayed correlation operation and a signal power calculator using the received input samples less than or equal to a zero-padded suffix of length M. We investigate the detailed characteristics of the proposed packet detector. In this paper, the performance of a class of packet detection algorithms in the ultra-wideband (UWB) channel environments is also studied. The best packet detection algorithm for the multi-band orthogonal frequency division multiplexing (MB-OFDM) UWB transmission is determined through analysis and extensive simulations. The results of analysis show that the proposed packet detection structure has advantages in the hardware complexity as well as performance when compared with the existing packet detection structures. In order to effectively conduct the packet detection before the automatic gain control (AGC) mode, we investigate the effects of both a frequency offset and the initial gain level of a variable gain amplifier (VGA) on the performance of the packet detection. We also suggest a VGA gain control technique to enhance the performance of packet detection.
