摘要： The present invention relates to an apparatus and method for detecting a data rate in a turbo decoder for a mobile communication system. When a rate selector selects one data rate among a plurality of data rates, a turbo decoder repeatedly decodes an input data frame within a predetermined repetition limit number using the selected data rate and outputs the decoded data. A CRC detector performs CRC check on the decoded data and outputs the CRC check result, and a decoding state measurer measures decoding quality depending on the decoded data and outputs decoding state information. A controller then sets the repetition limit number to a predetermined minimum value, controls the repetition limit number according to the decoding state information, controls the rate selector and determines a data rate of the input data depending on the CRC check result.

摘要： A device and method for rate matching channel-encoded symbols in a data communication system. The rate matching device and method can be applied to a data communication system which uses one or both of a non-systematic code (such as a convolutional code or a linear block code) and a systematic code (such as a turbo code). In one aspect, the rate matching device includes a plurality of rate matching blocks, the number of the rate matching blocks being equal to a reciprocal of a coding rate of a channel encoder. The rate matching device can rate match the symbols encoded with a non-systematic code or the symbols encoded with a systematic code, by changing initial parameters including the number of input symbols, the number of output symbols, and the puncturing or repetition pattern determining parameters.

摘要： A method and apparatus for deshuffling received shuffled data in a communication system supporting multi-level modulation. A transmitter encodes information bits and shuffles code symbols so that systematic symbols having a relatively high priority are disposed at high-transmission reliability positions and parity symbols having a relatively low priority are disposed at low-transmission reliability positions in a modulation symbol. A receiver demodulates received data and outputs a modulation symbol having a plurality of code symbols, stores the code symbols separately as systematic symbols and parity symbols in corresponding memory areas according to a deshuffling order corresponding to the shuffling, reads the stored code symbols, decodes the stored code symbols at a predetermined code rate, and thus outputs an packet.

摘要： A method and apparatus for mapping a stream of bits output from an encoder to a stream of bits for 2m-ary modulation. The method and apparatus divides the stream of bits from the encoder into a first period and a second period. The first period includes bits with higher priority in the stream of the bits output from the encoder, and the second period includes bits with lower priority. The method and apparatus maps the bits existing in the first period to bit positions with higher reliability in a stream of m bits representing each of the bits for 2m-ary modulation, and maps the bits existing in the second period to bit positions with lower reliability in the stream of m bits.

摘要： An apparatus and method for soft-combining demodulated symbols in a mobile communication system. In the mobile communication system, a transmitting apparatus modulates symbols in different modulation schemes and a receiving apparatus demodulates the modulation symbols in correspondence with the modulation schemes. The soft symbol combining apparatus includes an RWF calculator, an RWF controller, and a soft symbol controller. The RWF calculator calculates an energy of a modulation symbol from each of the modulation schemes and determines relative ratios of the energies to be RWFs for the modulation schemes. The RWF controller multiplies soft metrics of the demodulated soft symbols by the RWFs. Finally, the soft symbol controller combines the multiplied soft metrics.

摘要： A method and apparatus provide a broadcast parameter message in a mobile communication system providing a broadcast service. If the provided broadcast service is time domain multiplex (TDM)-multiplexed, a message generator generates the broadcast parameter message by setting a field indicating the TDM multiplexing, setting a field indicating a position of the broadcast service in each sub-buffer, setting a field indicating whether one sub-buffer includes one service and a field indicating validity of the field, and setting a field exclusively indicating actual broadcast service data stored in one sub-buffer. A transmitter modulates the broadcast parameter message and provides the modulated broadcast parameter message to a terminal that receives the broadcast service.
