<p>PROBLEM TO BE SOLVED: To enhance interference elimination characteristic by reducing the effect of a hard decision error. SOLUTION: In the case that a result of hard decision by interference estimation units 20b-1-20b-3 differs between a concerned stage and its pre-stage and the hard decision of the concerned stage has an error, the concerned stage outputs '0' as a chip replica signal on the basis of a control signal outputted from a decision error estimation section 10b and the concerned stage outputs its own chip replica signal in other cases. Furthermore, in the case that a result of hard decision differs between a concerned stage and its pre-stage and the hard decision of the concerned stage has an error, a symbol replica signal outputted from interference estimation units 20a-1 to 20a-3 is outputted as a received symbol replica signal and in other cases, the received symbol replica signal of the concerned stage is outputted.</p> |
