    摘要: Methods and apparatuses are provided for achieving maximum diversity gain through channel coding based on a Low-Density Parity-Check (LDPC) code in a multiple antenna communication system. A method includes determining a parity-check matrix; generating a codeword using the parity-check matrix; puncturing a part of an information word; dividing a parity into a plurality of partial parities based on a number of transmit antennas; transmitting an unpunctured part of the information word and a partial parity over a first antenna; and transmitting at least one other partial parity over at least one other transmit antenna.

    摘要: An encoding apparatus and method in a communication/broadcasting system are provided. When an encoding symbol is generated using at least one source symbol from among total source symbols to be encoded, encoding symbols are generated by using each of the total source symbols with a uniform probability before repeatedly using any of the total source symbols.

    摘要: A wireless broadcast communication system includes a transmitter that provides broadcast services via a plurality of frames based on inband signaling, and a receiver that switches a sleep mode to an active mode and receives the target broadcast packets, according to the timing information. The receiver is repeatedly switched to the sleep mode according to the timing information. The system uses the scheduling information to detect broadcast packets via a plurality of frames, thereby enhancing the use efficiency of the scheduling information. Although the receiver fails to receive scheduling information via a particular frame, it can detect a position of a broadcast packet using the stored scheduling information.

    摘要: An apparatus and method for controlling a transmission mode in a MIMO mobile communication system are provided. In a receiver in the MIMO mobile communication system, an error checker checks errors in received data and outputting an error check result. A feedback portion adaptively changes a threshold associated with a channel state according to the error check result, and determines a transmission mode by comparing the changed threshold with a measured CQI, and feeds back transmission mode information to a transmitter.
