    Abstract: An apparatus is provided for channel encoding in a communication system using an LDPC code. The apparatus includes at least one processor configured to encode input bits using a Bose-Chaudhuri-Hocquenghem (BCH) code, shorten one or more bits of the encoded input bits according to a number of bit groups to be shortened and an order among a plurality of orders according to which the bit groups are shortened, wherein the number of bit groups to be shortened is based on a number of bits to be shortened which is based on a number of the encoded input bits, encode information bits including the encoded input bits and the shortened one or more bits, using an LDPC code to generate parity bits, and puncture one or more bits in the parity bits based on a puncturing parameter among puncturing parameters; and a transmitter configured to transmit a signal that is generated from the encoded information bits based on the punctured one or more bits. The plurality of orders are based on the puncturing parameters and include a first order and a second order that is different from the first order.

    Abstract: A method is provided for channel encoding in a communication system using a Low-Density Parity Check (LDPC) code. The method includes grouping information bits into a plurality of groups; determining an order of the plurality of groups to be shortened, based on whether a specific region in a frame is to be LDPC-encoded, where the specific region has a different ratio of a number of bits to be shortened to a number of bits to be punctured; determining a length of an information word to be obtained by shortening the plurality of groups; shortening the plurality of groups on a group basis in the determined order based on the determined length of the information word; and LDPC-encoding a shortened information word.

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

    Abstract: Methods and apparatuses for transmitting/receiving control information in a system in which multiple frequencies are used to carry multiple services by means of transmission frames, which are constituted of time resources and/or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel. The service traffic for each non-primary service traffic may include control information for a primary service. Thus, even when a receiver changes the current service to a target service, control information necessary to detect the location of the target service in a frame and demodulate the target service can be acquired, and thus a service change can be made without reading a separate control channel.
