Wireless communication device and operating method of the same

An operating method of a wireless communication device including a plurality of antennas configured to transceive a signal, the operating method comprising:

• detecting a first interference for N resource blocks (RB) of the signal;
• based on the first interference being detected, performing a first whitening validation on the first interference;
• detecting a second interference, based on a result of the first whitening validation;
• based on the second interference being detected, performing a second whitening validation on the second interference;
• and
• performing whitening filtering according to results of the first whitening validation and the second whitening validation.

An electronic device comprising:

• a communication circuit configured to transceive a signal using a plurality of antennas;
• a processor configured to:
• detect a first interference for N resource blocks (RB) of the signal;
• based on the first interference being detected, perform a first whitening validation on the first interference;
• detect a second interference, based on a result of the first whitening validation;
• and
• based on the second interference being detected, perform a second whitening validation on the second interference;
• a whitening filter circuit configured to perform whitening filtering according to results of the first whitening validation and the second whitening validation;
• and
• a whitening control circuit configured to change at least one threshold value related to detection of the first interference and the second interference, based on a remaining battery charge of the electronic device, the first whitening validation, and the second whitening validation.
