Title:

KNOWN SIGNAL DETECTION METHOD

Document Type and Number:

WIPO Patent Application WO/2018/042837

Kind Code:

A1

Abstract:

According to the present invention, Fourier transform is performed on a reception signal to obtain a first calculation value. Fourier transform is performed on a known signal to obtain a second calculation value. The first calculation value is divided by the second calculation value to obtain a third calculation value. Inverse Fourier transform is performed on the third calculation value to obtain a fourth calculation value. The maximum value of the amplitude of the fourth calculation value and a sample point at which the maximum value is obtained, are detected. The position of the known signal in the reception signal is detected from the sample point at which the maximum value is obtained.
