    Abstract: Disclosed are a memory device that performs offset calibration and a method of operating the memory device. The memory device includes an input/output pad configured to receive data from a device external, an on-die termination (ODT) circuit connected to the input/output pad, a plurality of receivers connected to the ODT circuit and configured to receive the data from the input/output pad, an offset calibration circuit configured to perform an offset calibration operation on data output from the plurality of receivers and output an offset correction, a first switch configured to provide a first voltage to the plurality of receivers, and a second switch configured to provide a second voltage to the plurality of receivers. During the offset calibration operation, the plurality of receivers receive a third voltage in response to the ODT circuit being enabled and the first voltage through the first switch.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate than 4G communication systems such as LTE systems. The disclosure relates to a method and device for dynamically selecting, or simultaneously performing, PAC code-based Fano decoding and/or list decoding in a wireless communication system. The method for performing PAC code-based decoding by a reception device in a wireless communication system comprises identifying a specific criterion variable related to a channel state for selecting at least one of Fano decoding or list decoding for a signal received from a transmission device, comparing the specific criterion variable related to the channel state with a threshold, performing the Fano decoding in case that the specific criterion variable related to the channel state satisfies the threshold, and performing the list decoding in case that the specific criterion variable related to the channel state does not satisfy the threshold.

    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method performed by a transmitting node in a wireless communication system may include encoding a plurality of information bits using a plurality of cyclic redundancy check (CRC) bits, interleaving the plurality of the information bits and the plurality of the CRC bits using an interleaving pattern, generating a codeword by convolution-encoding and polar-encoding the plurality of the interleaved information bits and the plurality of the interleaved CRC bits, and transmitting the codeword to a receiving node. The interleaving pattern may correspond to a matrix generated based on a size of the plurality of the information bits and a size the plurality of the CRC bits.
