  • Patent number: 9294228
    Abstract: An apparatus and method for detecting high speed shared control channel of a communication terminal is provided, which recognizes decoding reliability for each of high-speed shared control channel by decoding each of a plurality of high-speed shared control channels; decides a maximum and a minimum in the decoding reliability, calculates a difference between the maximum and the minimum to compare the calculated difference with a preset critical value; and detects and processes a high-speed shared control channel corresponding to the maximum, when the difference exceeds the critical value. Accordingly, even though the wireless environment is inferior, the decoding reliability of an HS-SCCH can be more accurately decided in an HS-SCCH detection apparatus of the communications terminal and the detection performance of the HS-SCCH can be improved in a communication terminal.

  • Patent number: 8510609
    Abstract: An apparatus and method for rate dematching in a communication system are provided. The apparatus includes an input sequence generator, an error calculator, and a puncture/repetition determiner. The input sequence generator calculates if current input data among data, which are input in interleaved sequence, corresponds to any nth sequence among before-interleaved sequence. The error calculator calculates an error for the current input data using the calculated sequence. The puncture/repetition determiner determines type of the current input data using the error for the current input data.

  • Publication number: 20080034274
    Abstract: Provided are a decoder and decoding method wherein decoding is performed in consideration of input message characteristics. The decoder includes a fixed information checking unit for checking whether input data corresponds to fixed information; and a Branch Metric Calculation (BMC) unit for allowing the fixed information checking unit to check whether the input data corresponds to the fixed information upon receiving the input data, and if the input data corresponds to the fixed information, for computing branch metrics for a path by the use of the fixed information. Accordingly, error correction is improved.

  • Publication number: 20070083587
    Abstract: An apparatus and method for calculating a square root are provided. The square root calculation apparatus calculates an approximated square root for an input value. An integer detector detects a position of a non-zero most significant bit (MSB) from the input value, and outputs an arbitrary integer value. A first approximated linear square root calculator outputs an approximated square root by applying the input value and an even integer value output from the integer detector to a first linear approximation equation. A second approximated linear square root calculator outputs an approximated square root by applying the input value and an odd integer value output from the integer detector to a second linear approximation equation. A controller controls a multiplexer such that the approximated square roots calculated by the first and second approximated linear square root calculators are output according to whether the integer value output from the integer detector is an even number or an odd number.
