    摘要: In a signal processing apparatus adapted to process a signal transmitted via a transmission path, distortion of a waveform of a signal value of a specific symbol is predicted on the basis of a characteristic of distortion depending on values of symbols transmitted before the specific symbol, and the distortion is removed from the waveform of the received signal thereby producing a distortion-removed waveform. A comparison value is calculated for each allowable value of the specific symbol by subtracting a predicted signal value of the specific value from the distortion-removed waveform. A symbol value corresponding to the smallest comparison value is determined as the value of the specific symbol. An error suspicion level value indicating the degree of suspicion of being incorrect is calculated for each of the predetermined number of symbols, and already determined values of symbols are corrected in accordance with the error suspicion level values.

    摘要: In a signal processing apparatus adapted to process a signal transmitted via a transmission path, an acquisition unit acquires a signal value of a specific symbol from a signal transmitted via the transmission path, and a prediction unit predicts a signal value of the specific symbol for each of values allowed to be taken by the specific symbol, on the basis of values taken by a plurality of symbols transmitted before the transmission of the specific symbol and on the basis of characteristics of influences of the signal values of the plurality of symbols transmitted before the transmission of the specific symbol on the signal value of the specific symbol. A determination unit determines the value taken by the specific symbol, on the basis of the signal value of the specific symbol acquired by the acquisition unit and the predicted values for respective values allowed to be taken by the specific symbol.
