发明名称 Sequence estimation for multicarrier signals
摘要 <p>A receiving apparatus is disclosed, which is capable of applying maximum likelihood sequence estimation precisely, with a simple configuration. The characteristics of the transmission line of each symbol group are estimated on the basis of the amplitude and the phases of the pilot symbols which have been extracted from the reception symbol group, and the information symbol group is restored from the reception symbol group on the basis of the result of the estimation, and the coded bit group which has been restored from the information symbol group is multiplied by the weighting factor and caused to reflect the reliability of the transmission line of each symbol group, and maximum likelihood sequence estimation is applied to the coded bit group which is reflecting the reliability, and thereby the information bit sequence is restored; as a result, by the use of simple configuration, influences given at the transmission line can be eliminated and so the information symbol group can be restored exactly, besides, the reliability of the transmission line of each symbol group can be reflected on the coded bit group, in this way, maximum likelihood sequence estimation can be applied more precisely. &lt;IMAGE&gt;</p>
