Apparatus and method for detecting packet arrival time

   
   

A detector for detecting packet arrival time for packets received by a Home Phoneline Network Alliance (HPNA) receiver. The detector correlates received preamble symbols with stored preamble symbols and generates an estimation of the packet arrival time when the entire transmitted preamble has arrived at the receiver. The estimation of the packet arrival time is defined on a symbol period boundary. The detector includes a complex correlator with a simplified structure based on characteristic of the received HPNA signal.

Um detetor para detectar o tempo de chegada do pacote para os pacotes recebidos por um receptor home do alliance da rede de Phoneline (HPNA). O detetor correlaciona símbolos recebidos do preamble com os símbolos armazenados do preamble e gera um estimation do tempo de chegada do pacote em que o preamble transmitido inteiro chegou no receptor. O estimation do tempo de chegada do pacote é definido em um limite do período do símbolo. O detetor inclui um correlator complexo com uma estrutura simplificada baseada na característica do sinal recebido de HPNA.
