摘要： An apparatus and method for encoding a channel in a communication system using a Low-Density Parity-Check (LDPC) code. The method includes determining a number of parity bits to be subjected to puncturing; dividing the parity bits at predetermined intervals, and determining a number of puncturing bits, which are subjected to puncturing within the predetermined intervals; determining positions of puncturing parity bits corresponding to the determined number of puncturing bits; and repeatedly performing puncturing on the puncturing parity bits corresponding to the determined positions at the predetermined intervals. The predetermined intervals are determined by dividing a length of parity bits by a length of one column group in a parity-check matrix.

摘要： Disclosed is a method and apparatus for transmitting/receiving control information in a system in which one or more Radio Frequencies (RFs) are used to carry multiple services through a frame constituted by time resources or time-frequency resources. Control information regarding frame configuration information is not transmitted over a separate control channel but over a data channel through which to transmit primary service traffic among all service traffic, and each non-primary service traffic other than the primary service traffic includes 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.

摘要： A method for transmitting and receiving broadcast signals in a radio broadcasting communication system is provided together with an associated apparatus. The transmitting method includes creating a frame having a preamble slot, a data slot and a control slot, and sending the created frame. The control slot has information for assigning the data slot to one of an uplink and a downlink. The receiving method includes receiving such a frame wherein the control slot has scheduling information for each user, and extracting the data slot from the received frame by using the scheduling information in the control slot. These methods may realize an interactive broadcasting by separately employing broadcast signals for the uplink and downlink.
