Abstract: Provided are an image signal processor, an operating method of the image signal processor, and an application processor including the image signal processor. The image signal processor includes a downscaling circuit configured to generate a first image signal by downscaling an input image signal; an image processing engine configured to generate a second image signal by performing a plurality of image processing operations on the first image signal; a first upscaling circuit configured to generate a third image signal by upscaling the second image signal; a second upscaling circuit configured to generate a fourth image signal by upscaling the first image signal; a correction information generating circuit configured to generate an image information signal by extracting information on image quality loss of the third image signal from the input image signal and the fourth image signal; and a recomposition circuit configured to generate an output image signal by recomposing the third image signal and the image information signal.

Abstract: The disclosure relates to detection and control of remote interference due to an atmospheric ducting phenomenon. More specifically, a method of a first base station, according to one embodiment of the disclosure, for controlling interference due to atmospheric ducting in a wireless communication system includes: receiving a sequence from at least one second base station; identifying the at least one second base station corresponding to the sequence; estimating a channel for the at least one identified second base station, based on the sequence; and controlling a beam in a direction corresponding to the at least one identified second base station, based on a result of the channel estimation.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system, such as long-term evolution (LTE). The disclosure provides decoding of a low-density parity-check (LDPC) code in a wireless communication system, and a decoding method of the LDPC code may include receiving a codeword, performing decoding iterations on the codeword a predefined maximum number of times using a parity check matrix, performing partial decoding using a partial area of the parity check matrix, and determining decoding success or failure of the codeword based a result of the partial decoding.

Abstract: The present invention relates to a preamble signal detection method of a receiving device, and a device therefor. A preamble signal detection method of a receiving device, according to one embodiment of the present disclosure, can comprise the steps of: receiving a plurality of preamble signals for random access through a physical random access channel (PRACH); determining at least one preamble signal corrupted by an interference signal among the received plurality of preamble signals; combining the remaining preamble signals excluding the at least one corrupted preamble signal among the plurality of preamble signals; and detecting a peak value of the combined preamble signals. The study was performed with the support of the “Governmental Department Giga KOREA Business” of the Ministry of Science, ICT and Future Planning.

Abstract: An interference cancellation method and apparatus of a base station is provided for use in a wireless communication system, which includes receiving a first signal by a first antenna and a second signal by a second antenna, measuring interference amounts in the first signal and the second signal based on a result of channel measurement performed on the first signal and the second signal, and generating a third signal as a target of decoding by adjusting channel parameters associated with channel conditions of the first antenna and the second antenna based on the measured interference amounts. The channel parameters are generated based on the channel measurement result.
