Title:
INTERFERENCE CANCELLATION APPARATUS AND METHOD ROBUST TO FREQUENCY OFFSET IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/147520
Kind Code:
A1
Abstract:
Provided are an interference cancellation apparatus and an interference cancellation method robust to a frequency offset in a wireless communication system. At this time, the interference cancellation apparatus receives a signal modulated according to a predetermined modulation scheme, estimates a carrier frequency offset on the basis of a preamble and a pilot of the received signal, detects an optimal filter coefficient matched with the estimated carrier frequency offset among optimum filter coefficients calculated for each of a plurality of carrier frequency offsets, and demodulates the received signal with a demodulation scheme corresponding to the modulation scheme by using the detected optimal filter coefficient in a reception filter and thus detects data.
