<p>In a signal demodulating and decoding apparatus, plural demodulating means and decoding means corresponding to plural modulation systems are provided respectively, and these are operated at the same time and respective decoding results are outputted. Further, the signal demodulating and decoding apparatus evaluates decision error amounts of respective demodulating means and selects the decoding data by the demodulating means and the decoding means having the least decision error amount, and when operation means for adaptively correcting the parameters used within the demodulating means is provided so that decision errors on inputting the decision results of the demodulating means into the decoding means are made small, the decision error amount inputted to the operation means is selected similarly to the above. <IMAGE></p> |
