Patent ID: 7936712

Claim:
A signal processing apparatus adapted to process a signal transmitted via a transmission path in which a signal value of a specific symbol is influenced in a stationary manner by signal values of a plurality of symbols transmitted before the transmission of the specific symbol, comprising: acquisition means for acquiring the signal value of the specific symbol from a signal transmitted via the transmission path; prediction means for predicting the 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 the 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; determination means for determining the value taken by the specific symbol, on the basis of the signal value of the specific symbol acquired by the acquisition means and the predicted values given by the prediction means for respective values allowed to be taken by the specific symbol, receiving means for receiving a test signal including a plurality of symbols taking predetermined values; and characteristic acquisition means for acquiring a characteristic of an influence of a signal value of a symbol, included in the symbols of the test signal, transmitted before the transmission of the specific symbol on the signal value of the specific value, on the basis of the signal value of the specific symbol of the test signal received by the receiving means.
