摘要： PROBLEM TO BE SOLVED: To provide a new methodology for blind detection of a transmission format of a convolution-encoded signal.
SOLUTION: The method for the blind detection of the transmission format of the convolution-encoded signal comprises the step of decoding the signal using a maximum a posteriori algorithm. Further the decoding step includes the steps of: decoding the signal by considering possible MF reference formats and delivering MF corresponding groups of soft output information; calculating from each group of soft output information a CRC (Cyclic Redundancy Check) word and comparing the calculated CRC word with the transmitted CRC word; selecting all the groups for which the calculated CRC word is equal to the transmitted CRC word; and selecting the actual transmission format of the encoded signal from at least one soft input information among the last pieces of the soft input information of each selected group.

摘要： PROBLEM TO BE SOLVED: To provide a method of dynamically switching a decoding scheme to operate an inclusive turbo decoder in a mode of best performance at all the time in accordance with transmission conditions.
SOLUTION: In the method of decoding an incident turbo-code encoded signal in a receiver, quality information representative of the conditions of the channel state estimation is dynamically determined, and the quality information is dynamically compared with a predetermined criteria for defining a binary result corresponding to good or bad estimation conditions. As a result, when the good conditions are present, a maximum-a-posteriori algorithm in the logarithmic domain, called LogMAP algorithm, is selected and when the bad conditions are present, an approximate algorithm of the maximum-a-posteriori algorithm in the logarithmic domain, called MaxLogMAP algorithm, is selected. Such a selection is dynamically carried out.

摘要： PROBLEM TO BE SOLVED: To perform automatic frequency control to a local oscillator in a DS-CDMA receiver.
SOLUTION: A residual frequency error f
e is measured with respect to each symbol, the error is filtered, and the frequency of a local oscillator is corrected by the filtered error. A first measured residual frequency error f
e1 is stored, an average of absolute values of following residual frequency errors of a predetermined number is measured, the average is compared with a predetermined threshold and when the average is equal with or larger than the threshold, before measuring the next residual frequency error associated with the next symbol, the frequency of the local oscillator is corrected by using the error equal to -sgn(f
e1 )(1/T-|f
e1 |) (sgn is sign function, || indicates absolute value and T indicates continuation term of symbol).
