Title:
RECEIVER
Document Type and Number:
WIPO Patent Application WO/2019/234875
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a receiver capable of estimating a frequency deviation with high accuracy even in an environment in which delay waves are generated. In the receiver of the present invention, a signal switching unit (2) extracts a preceding wave reception signal (S5) and a delay wave reception signal (S6), on the basis of timing information from a preceding wave/delay wave timing estimation unit (3). Further, by taking the preceding wave reception signal (S5) and the delay wave reception signal (S6) as targets for evaluation, first to nth likelihood representative values (D71 to D7n) are determined through processing of first to nth frequency correction units (41 to 4n), first to nth preceding wave likelihood value generation units (51 to 5n), first to nth delay wave likelihood value generation units (61 to 6n), and first to nth likelihood processing units (71 to 7n).
