摘要： The present disclosure is related to detecting a start frame delimiter. A received data packet is correlated with a known sequence, which provides a first correlation result. The received data packet is correlated with a predefined sequence, which yields at least a second correlation result. The data packet comprises at least a preamble portion and a header portion, whereby the preamble portion comprises the start frame delimiter. The predefined sequence is determined according to the preamble pattern. The method further comprises comparing the first correlation result with the second correlation result and comparing the first correlation result with a given threshold. The process of correlating will be continued until two criteria are met: the first correlation result is larger than the threshold and larger than the at least second correlation result. Only then it is decided that the start of frame delimiter pattern has been detected.
