Abstract: The present disclosure relates to a method of reducing a Peak to Average Power Ratio (PAPR) in a communication device, and more particularly, to a method of Crest Factor Reduction (CFR) processing of a signal in order to reduce a PAPR in a communication device such as a repeater. The communication device includes: a first CFR module configured generate a first processed signal by CFR processing an original signal; and a second CFR module configured generate a second processed signal by CFR processing the first processed signal, wherein the first processed signal is generated using a first sampling rate, and the second processed signal is generated using a second sampling rate. According to the disclosure, even a communication device with a low sampling rate may effectively remove a peak component of an input signal.

Abstract: Provided is an SINR measurement method of a repeater, the SINR measurement method including: obtaining SSBs from a plurality of base stations; obtaining cross-correlation for each of PSS symbols included in the obtained SSBs; measuring noise power based on the obtained SSBs; obtaining signal power and interference signal power based on a dot product of the cross-correlation for each of the PSS symbols; and measuring the SINR based on the signal power, the interference signal power, and the noise power.
