Abstract:
1. A receiving apparatus comprising: a reception section that receives a result of transmitting a transmission signal obtained by modulating a known signal and a data signal and outputs said result as a reception signal; a prediction section that predicts a transmission characteristic; a compensation section that compensates that portion of said reception signal which corresponds to said data signal and which has not been compensated yet, using a predicted portion of said transmission characteristic, and outputs said compensated portion as a compensated data signal; a demodulation section that demodulates said compensated data signal and outputs said demodulated signal as a demodulated data signal; and a modulation section that modulates said demodulated data signal and outputs said modulated signal as a modulated data signal, whereby said prediction section (a) compares that portion of said reception signal which corresponds to said known signal with a result of modulating said known signal and compares that portion of said reception signal which corresponds to said data signal with that portion of said modulated data signal which corresponds to said data signal to acquire a time series of comparison results, (b) replaces a value in said time series of comparison results which satisfies a predetermined exclusion condition with an old value of said time series of comparison results, (c) averages a time series of comparison results resulting from that replacement, and (d) lets a result of that averaging be a predicted transmission characteristic.
