ABSTRACT:
In a receiving apparatus in a multicarrier communication system for transmitting data independently via a plurality of subchannels, (1) a soft-decision target value lnD0is calculated, this being the difference between the probability that data received from a subchannel of interest is one of two values and the probability that the data is the other of the two values; (2) a non-linear operation is performed using degrees of coupling α1, α2with other subchannels and soft-decision target values lnD1, lnD2that have entered from receivers on the other channels, and the soft-decision target value lnD0on the subchannel of interest is adjusted subchannel by subchannel based upon results of the non-linear operation; and (3) a decision is rendered on receive data based upon the soft-decision target value that has been adjusted.
