    Abstract: The disclosure proposes a technique for achieving validity decision performance of a suitable level in communication and broadcasting systems using a polar code. The polar code is a channel code in which it is difficult to use a syndrome check due to a successive cancellation (SC)-based decoding operation and coding structure. Accordingly, in the communication of the related art and broadcasting systems using the polar code, a validity check of a decoding result has been performed by using a path-metric (PM) generated during decoding and a concatenated error detection code, such as a cyclic redundancy check (CRC) code. However, it is difficult to achieve target error detection performance only via such methods when the length of the CRC code is short or when input and output lengths of a code are short. In this regard, an embodiment of the disclosure proposes a method for obtaining a Euclidean distance-based metric between a received signal and a decoded signal by using an estimated codeword output bit sequence, and performing post error detection based on this.

    Abstract: An image sensor includes a device isolation layer disposed in a substrate and defining pixel regions, and a grid pattern on a surface of the substrate. The grid pattern overlaps the device isolation layer between adjacent pixel regions in a direction perpendicular to the surface. The grid pattern has a width less than a width of the device isolation layer.

    Abstract: A pre-5th generation (5G) or 5G communication system supports higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE) is provided. A method for operating a first device in a wireless communication system includes generating a first bit sequence, generating a second bit sequence including at least one of the first bit sequence, at least one cyclic redundancy check (CRC) bit, at least one frozen bit, or at least one parity check (PC) bit, generating a transmission bit sequence by performing a polar encoding and a rate matching for the second bit sequence, and transmitting, to a second device, the transmission bit sequence. A length of the transmission bit sequence is equal to or greater than a sum of a length of the first bit sequence, a number of the at least one CRC bit and a number of the at least one PC bit.
