Abstract: A method and an apparatus are provided for receiving signaling information in a digital broadcasting system. The method includes receiving a frame including a first coded block, a second coded block, and at least one physical layer pipe (PLP) data; decoding the first coded block to identify first signaling information for a physical layer; and decoding the second coded block to identify second signaling information. The first signaling information has a fixed number of bits. The second signaling information has a variable number of bits. The first signaling information includes information indicating a forward error correction (FEC) type of the second signaling information for receiving the second signaling information. The second signaling information includes information indicating a modulation scheme used for related PLP data.

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 a long term evolution (LTE). A method includes decoding a codeword corresponding to a preset decoding scheme to detect reliability information of each of codeword bits included in the codeword, wherein at least one of a number of quantization bits and a range of a quantization level used for detecting reliability information in the decoding scheme is determined based on a degree of a node on a bipartite graph of a low density parity check (LDPC) code.

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.

Abstract: A method and an apparatus are provided for decoding a channel in a communication system using a LDPC code. A shortening pattern and a puncturing pattern are determined based on a received signal. A value of a shortened bit is set to 0 according to the determined shortening pattern, erasures are set according to the determined puncturing pattern, and LDPC decoding is performed, when bits exist which have been used to perform shortening or puncturing. Determining the shortening pattern and the puncturing pattern includes setting a predetermined ratio of the number of punctured bits to the number of shortened bits.
