Title:
タイミング検出方法及び無線通信装置
Document Type and Number:
Japanese Patent JP7354297
Kind Code:
B2
Abstract:
[Problem] To enable stable timing synchronization to be guaranteed even when a narrow-band disturbance wave exists. [Solution] A wireless communication device on the receiving side is provided with: memories 103-1, 103-2 in which are stored a plurality of correlated signals that are time-domain signals of mutually different frequency components from among preamble signals; correlators 102-1, 102-2 for computing the correlation of a received signal with each of the plurality of correlated signals; and a peak detector 105 for detecting the reception timing of a preamble signal using at least one of the results of correlation computation obtained by the correlators 102-1, 102-2.
