Title:
RECEIVING DEVICE, CONTROL CIRCUIT, STORAGE MEDIUM, AND RECEIVED SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/161495
Kind Code:
A1
Abstract:
A receiving device (100) of a radio communication system in which the distortion characteristic of a received signal varies over time is provided with an equalization processing unit (105) which performs equalization processing of the received signal, a demapping unit (108) which demaps the equalization-processed reception signal acquired from the equalization processing unit (105), and a signal information identifying unit (111) which identifies information indicating the distortion state of the received signal on the basis of a demapping processing result acquired from the demapping unit (108), to generate signal identification information, wherein the equalization processing unit (105) is provided with: a plurality of equalization filter units connected in parallel; a filter switch control unit (116) which switches whether to combine the filter outputs from the plurality of equalization filter units, on the basis of the signal identification information; and a filter coefficient combining unit (115) which combines the filter coefficients of the plurality of equalization filter units on the basis of the signal identification information.
