Patent ID: 7020459

Claim:
A receiver configured to receive a signal that has been encoded, interleaved, burst mapping processed, and modulated via a wireless channel, the receiver comprising: a modulation scheme judging unit configured to judge a modulation scheme for a burst based on a part of known sequence in the burst; a soft decision unit configured to receive the judged modulation scheme from the modulation scheme judging unit and the burst, and to output a soft decision value for the burst based on the judged modulation scheme and the burst; a soft decision value alteration controlling unit configured to receive the judged modulation scheme from the modulation scheme judging unit, and to control a change of the soft decision value if the judged modulation scheme is determined to be incorrect; a soft decision value storing and correcting unit configured to store the soft decision value output by the soft decision unit, and to change the soft decision value under the control of instructions output by the soft decision value alteration controlling unit; a deinterleaving unit configured to deinterleave the stored soft decision value; and a decoding unit configured to decode the soft decision value as after the deinterleaving.
