  • Patent number: 8332734
    Abstract: 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.

  • Patent number: 7933371
    Abstract: Method and Apparatus for controlling combining coefficients of multiple receive antennas according to the channel conditions in a mobile communication system, to improve data restoration performance. A mobile station detects preamble, pilot and data from a signal received from a base station via the multiple receive antennas, measures a channel correlation from the detected preamble, classifies time-domain/frequency-domain intervals having a channel correlation exceeding a predetermined threshold as calculation regions, and calculates MMSE coefficients for the calculation regions. In this way, the mobile station finds the optimal coefficients for combining the signal received via the multiple receive antennas, thereby optimizing the reception performance.
