Title:
通信装置、並びに適応等化装置
Document Type and Number:
Japanese Patent JP4748211
Kind Code:
B2
Abstract:
A communication device is provided for receiving a packet including a preamble part having a continuous waveform, a sync part having a specific pattern and a data part, which has been modulated by changing electrical load. The communication device includes: a preamble detection unit for detecting the preamble part from a received signal to extract sampling timing based on the continuous waveform; a sync detection unit for detecting the sync part from the received signal based on the sampling timing to output a timing signal indicating a start position of the sync part; a delay buffer for giving a delay to the received signal so that the head of the sync part is not outputted until the detection of the sync part is determined; an adaptive equalization unit for performing adaptive equalization using the sync part based on the timing signal by inputting the delayed received signal; and a decoding unit for performing decoding processing of an equalized output signal from the adaptive equalization unit.
