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： An apparatus and method for carrier frequency synchronization in an Orthogonal Frequency Division Multiplexing (OFDM) system are provided for correcting an initial carrier frequency offset in the OFDM system. A metric generator for frequency estimation performs a first accumulation process for a value computed by multiplying a Phase Reference Symbol (PRS) generated from a reception stage by a Fast Fourier Transform (FFT) output signal for an OFDM symbol in a PRS position within a frame, acquires a differential symbol from a product of adjacent FFT output symbols, performs a second accumulation process for a real part extracted from the differential symbol, and outputs a metric value for the frequency estimation. A maximal value-related index generator compares metric values for initial frequency estimation within a predetermined frequency offset estimation range, and selects and outputs a maximal metric value as a frequency offset estimate.

摘要： An apparatus and method are provided for normalizing input soft metric to a channel decoder in a wireless communication system. A demapper generates soft metric using an in-phase component (Xk) and a quadrature component (Yk) of a received modulated symbol (Rk), a channel fading coefficient (gk) and a constant value (c) defined by a modulation order of the received modulated symbol. A normalizer receives the soft metric, computes a normalized log likelihood ratio (LLR) by multiplying the soft metric by a ratio of the constant value to a noise variance value, transforms the normalized LLR into a desired range and a desired number of bits, and outputs an input LLR of the channel decoder.
