Abstract: An operating method of a wireless communication device includes: receiving a reference signal transmitted from a second wireless device; calculating a reference noise value based on the reference signal; calculating, by the processor, a noise threshold value based on the reference noise value; receiving a first data signal transmitted from the second wireless device; calculating a data noise value based on the first data signal; comparing, by the processor, the data noise value with the noise threshold value; determining whether interference occurs in a target symbol based on a result of the comparison; adjusting the noise threshold value based on the data noise value when it is determined that the interference has occurred in the target symbol; and receiving a second data signal transmitted from the second wireless device, and using the adjusted noise threshold value in processing the second data signal.

Abstract: An ultrapure water supply apparatus includes a first filtering device, a second filtering device, a first tank between the first and second filtering devices, a third filtering device, a second tank between the second and third filtering devices, a fourth filtering device, a third tank between the third and fourth filtering devices, and a gas supply device connected to each of the first to third tanks and configured to supply an inert gas. Each of the first to third tanks includes a tank body and a breather valve coupled to the tank body and connected to a storage space in the tank body. Each of the first to fourth filtering devices includes at least one selected from an activated carbon filter device, an ion exchange resin device, a reverse osmosis membrane device, and a hollow fiber membrane device.

Abstract: A fluid supply includes a first fluid source configured to supply a first fluid, a second fluid source configured to supply a second fluid, a heat exchanger configured to exchange heat between the first fluid and the second fluid, a first fluid recovery tank configured to recover the first fluid that has passed through the heat exchanger, and a first transfer pipe configured to transfer the first fluid from the first fluid source to the first fluid recovery tank via the heat exchanger. The heat exchanger may be disposed at a vertical level higher than a vertical level of the first fluid recovery tank.
