    摘要: A method for detection of a control channel includes receiving data transmitted via the control channel. A control channel receive quality is estimated based on a metric difference between a metric of a known final trellis state and a minimum metric amongst the metrics of the trellis states based on the received data. It is decided whether or not to detect the control channel depending on the estimated control channel receive quality.

    摘要: Depending on the sequence of the decoded payload signal bits (am1, . . . , amA) and redundancy checking bits (pm1, . . . , pmL) which are produced by the Viterbi traceback, either some of these bits are inserted by means of a distribution device (1) from the front into a linear feedback shift register (10), or some of these bits are inserted by means of the distribution device (1) from the rear into a linear feedback shift register (10), or all of them are inserted into a linear feedback shift register (20) from the rear with the allocated coefficients being unchanged, or all of them are inserted into a shift register from the front with the allocated coefficients being inverted. This allows a redundancy checking process to be carried out on a transmitted data block in the shift register (10; 20) without temporary storage of the bits produced by the decoding process.

    摘要: In a method of decoding data symbols into codewords, reliability information of the data symbols is provided. A first group of symbols from a first set of groups of symbols is selected, wherein the first set of groups of symbols is defined by at least a first parity-check of a parity-check matrix of a linear block code which has been used to encode the data symbols. The selection is based on the reliability information. A second group of symbols from a second set of groups of symbols is selected, wherein the second set of groups of symbols is defined by at least a second parity-check of the parity-check matrix. The selection is based on the selected first group of symbols and the reliability information. At least a part of the codeword is composed on the basis of the first group of symbols and the second group of symbols.

    摘要: In the method for termination of turbo decoding, a plurality of first LLR values (Lai(k)) of a-priori information and a plurality of second LLR values (Lei(k)) of extrinsic information are called up. A value is determined for a decision variable which is characteristic of the number of mathematical sign discrepancies between the first Lai(k)) and the second Lei(k)) values. The turbo decoding is terminated if the number of mathematical sign discrepancies is less than or at least equal to a first number or if the number is greater than or at least equal to a second number.

    摘要: A method for calculation of path weights for the equalization of a data signal that is transmitted via a data channel whose power is regulated in a RAKE receiver is disclosed. In the method, at least one uncorrected path weight is calculated for the data signal that is transmitted via the data channel, using channel estimation results that have been obtained on the basis of a common pilot channel. The uncorrected path weight is corrected by multiplying it by a correction factor that contains a ratio of a data-channel-specific gain estimation to a pilot-channel-based gain estimation.
