Title:
TRANSMISSION PATH EQUALIZATION PROCESSING DEVICE, AND TRANSMISSION PATH EQUALIZATION PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/100092
Kind Code:
A1
Abstract:
The present invention suppresses deterioration in transmission path equalization processing accuracy. This transmission path equalization processing device is provided with: a transmission path estimation unit that calculates a first inverse modulation transmission path estimation value, a first interpolation transmission path estimation value, and a second interpolation transmission path estimation value; a noise estimation unit that, on the basis of a difference between each first inverse modulation transmission path estimation value and the first interpolation transmission path estimation value corresponding thereto, estimates noise electric power; and an MMSE equalization unit that, on the basis of the noise electric power, a resource element corresponding to a payload signal of a signal, and the second interpolation transmission path estimation value, performs MMSE standard equalization processing.
