    Abstract: An image sensor includes a semiconductor substrate having first and second surfaces facing each other and a first device isolation layer provided in the semiconductor substrate. The first device isolation layer defines pixel regions of the semiconductor substrate and includes first and second portions crossing each other. The first and second portions are provided to surround one of the pixel regions, and the first portion is provided to extend from the first surface of the semiconductor substrate toward the second surface and to have a structure inclined relative to the first surface.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. In an embodiment, a method for encoding information bits includes receiving the information bits, encoding the information bits by using a block code, and outputting a codeword generated as a result of the encoding. A length of the information bits is a maximum of 13 bits, and the block code is composed of a Walsh basis sequence and a mask basis sequence.

    Abstract: Fifth Generation (5G) or pre-5G communication system for supporting a data transfer rate higher than that of a fourth Generation (4G) communication system, such as Long Term Evolution (LTE), and subsequent systems. The present disclosure provides a method for transmitting a signal by a transmission terminal in a communication system using a Low Density Parity Check (LDPC) code. The method include receiving a change request for changing a coding rate of the LDPC code, from a reception terminal; determining a first coding rate based on the change request; and transmitting information on the first coding rate in respond to the change request, to a reception terminal, wherein the change request for changing the coding rate comprises at least one of information indicating a coding rate determined by the reception terminal, or information indicating a state of the reception terminal.
