DECISION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/140893
Kind Code:
A1
Abstract:
A soft assessment unit (60) makes a soft assessment of a demodulation result for each of a plurality of sub-carriers which configure a multi-carrier signal. An acquisition unit (64) acquires a weighting coefficient for each of the plurality of sub-carriers which configure the multi-carrier signal, based on the received power for each sub-carrier. If the received power of the sub-carrier is less than or equal to a threshold, the acquisition unit (64) acquires a weighting coefficient which is larger as the received power of the sub-carrier increases. If the received power of the sub-carrier is greater than the threshold, the acquisition unit (64) acquires the weighting coefficient which has a size less than or equal to the weighting coefficient when the received power of the sub-carrier is at the threshold. A weighting unit (66) weights the soft assessment result on a per sub-carrier unit basis with the weighting coefficient.
