Claim Text:
1. A wireless apparatus comprising: a first decoder to perform a first decoding process of calculating a first a posteriori value using a first a priori value and a first frame transmitted from a first apparatus, and output a hard decision value of the first a posteriori value and a first external value; a second decoder to perform a second decoding process of calculating a second a posteriori value using a second a priori value and a second frame transmitted from a second apparatus, and output a hard decision value of the second a posteriori value and a second external value, the second apparatus having received the first frame, the second frame containing re-encoded data of the first frame containing an error; an error rate estimator to estimate an error rate of one of the first frame or the second frame; a first a priori value calculator to calculate the second a priori value by correcting the first external value based on the error rate; and a second a priori value calculator to calculate the first a priori value by correcting the second external value based on the error rate.
