    摘要: A device generates coefficient data of an estimating equation for converting a first information signal to a second information signal. The device performs decimation on a teacher signal to generate a student signal and acquires plural training data items from the teacher signal corresponding to the second information signal and the student signal corresponding to the first information signal. For each training data item, a similarity determination unit acquires the similarity of the student signal with respect to the first information signal corresponding to a second information signal at a position of interest. Coefficient seed data, which are coefficient data of a generation equation including the similarity as a parameter, are determined using the training data items and the similarity. A coefficient data computing unit determines, based on the generation equation, coefficient data of the estimating equation using the coefficient seed data and a similarity value indicating the highest similarity.

    摘要: A pattern matching section compares reference taps supplied by one area extracting section with a reference tap component of a training pair pre-stored in a training-pair storing section, selects a training pair including a reference tap component having highest similarity to the reference taps, and supplies the selected training pair to a normal-equation generating section. Training pairs stored in the training-pair storing section include a SD signal and HD signal. A prediction-coefficient determining section obtains prediction coefficients by solving normal equations generated by the normal-equation generating section. A prediction calculating section produces a HD signal by applying the prediction coefficients to prediction taps extracted by another area extracting section.

    摘要: Disclosed herein is a signal processing apparatus that processes a signal transmitted over a transmission path that causes stationary distortion to occur in a waveform representing a signal value of a specific symbol in accordance with a value of a symbol transmitted before the specific symbol. The apparatus includes: storage means for storing distortion characteristics; acquisition means for acquiring the signal value of the specific symbol; correlation coefficient calculation means for calculating a correlation coefficient between the waveform representing the signal value of the specific symbol and each distortion characteristic; selection means for selecting a distortion characteristic(s) having a high correlation with the waveform representing the signal value of the specific symbol, based on the correlation coefficients; and determination means for determining the values of the symbols in the signal based on the combination of the values of the symbols corresponding to the selected distortion characteristic(s).

    摘要: An IC chip allows first communication for performing communication with all of the other IC chips, and second communication for performing communication while restricting communication parties. That is to say, the IC chip performs sending/receiving signals with a new communication arrangement with both the first communication which is a broadcasting arrangement and the second communication which is a communicatory arrangement. This enables the function upgrading electronic equipment to be performed easily, and enables flexible signal processing with a new communication arrangement.
