본 논문에서는 상호 상관기를 사용하는 고성능 및 하드웨어 효율적인 패킷 탐지 구조를 제시한다. M- 길이가 제로 패딩된 접미사보다 작거나 같은 수신된 입력 샘플을 사용하는 샘플 시간 지연 상관 연산 및 신호 전력 계산기 M. 제안된 패킷 탐지기의 세부적인 특성을 조사한다. 본 논문에서는 초광대역(UWB) 채널 환경에서 패킷 탐지 알고리즘 클래스의 성능에 대해서도 연구합니다. MB-OFDM(다중 대역 직교 주파수 분할 다중화) UWB 전송을 위한 최상의 패킷 감지 알고리즘은 분석과 광범위한 시뮬레이션을 통해 결정됩니다. 분석 결과, 제안하는 패킷 탐지 구조는 기존 패킷 탐지 구조와 비교하여 하드웨어 복잡도 및 성능 측면에서 장점이 있는 것으로 나타났다. 자동이득제어(AGC) 모드 이전에 패킷 검출을 효과적으로 수행하기 위해 주파수 오프셋과 가변이득증폭기(VGA)의 초기 이득 레벨이 패킷 검출 성능에 미치는 영향을 조사한다. 또한 패킷 감지 성능을 향상시키기 위해 VGA 이득 제어 기술을 제안합니다.

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.
