Wireless communication device for detecting interference and operating method of the same

An operating method of a wireless communication device, the operating method comprising:

• receiving at a receiver of a first wireless device a reference signal transmitted from a second wireless device;
• calculating, by a processor of the first wireless device, a reference noise value and a reference received value based on the reference signal;
• calculating, by the processor, a noise threshold value and a reception threshold value respectively based on the reference noise value and the reference received value;
• receiving at the receiver of the first wireless device a first data signal transmitted from the second wireless device, the first data signal including a first type block and a second type block;
• calculating, by the processor, a data noise value and a data received value based on the first data signal;
• based on whether interference occurs in a previous symbol before a target symbol, either comparing, by the processor, the data noise value with the noise threshold value, or comparing, by the processor, the data received value with the reception threshold value;
• determining, by the processor, whether interference occurs in the target symbol based on a result of the comparison;
• adjusting, by the processor, the noise threshold value and the reception threshold value respectively based on the data noise value and the data received value when it is determined that the interference has occurred in the target symbol;
• and
• receiving at the receiver of the first wireless device a second data signal transmitted from the second wireless device, and using the adjusted noise threshold value and reception threshold value in processing the second data signal.
