RECEPTION DEVICE, AND RECEPTION SIGNAL PROCESSING METHOD

WIPO Patent Application WO/2019/171551

A1

A reception device (100) is characterized by being provided with: an equalization processing unit (107) that includes a linear filter unit and a nonlinear filter unit and that performs an equalization process for a reception signal; a linear propagation path estimation unit (106) that performs propagation path estimation using a known signal included in the reception signal so as to calculate a filter coefficient of the linear filter unit; and a synchronization processing unit (120) that performs a synchronization process for correcting a frequency deviation, on the basis of a signal outputted by the equalization processing unit, wherein, when a predetermined condition is satisfied after execution of a first equalization process for outputting, to the synchronization processing unit, the reception signal on which filtering has been performed by the linear filter unit, the equalization processing unit (107) starts a second equalization process that is an adaptive equalization process for outputting, to the synchronization processing unit, a result obtained by adding the reception signal on which filtering has been performed by the linear filter unit and the reception signal on which filtering has been performed by the nonlinear filter unit.
