摘要： In a receiving apparatus in a multicarrier communication system for transmitting data independently via a plurality of subchannels, (1) a soft-decision target value lnD0 is 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, α2 with other subchannels and soft-decision target values lnD1, lnD2 that have entered from receivers on the other channels, and the soft-decision target value lnD0 on 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.

摘要： Two correlation signals which are obtained by computing correlations between two reference signals and a reception signal are inputted to a level-0 cell, the reference signals being generated on the basis of combinations of crosstalk coefficients. A level-1 soft judgment target signal is produced by using soft judgment target signals that are outputted by two sets of level-0 cells respectively and, similarly, a level (N+1) cell is formed by using two sets of level-N cells, whereby a soft judgment target signal creation portion with a hierarchical structure is constituted. A judgment unit outputs a soft judgment value of the target subchannel on the basis of the soft judgment target signal that is outputted by the level (N+1) cell, and judges a reception signal.

摘要： A reception device receives and demodulates, for each subchannel, data transmitted independently via three subchannels, which are a subchannel of interest and the two upper and lower adjacent subchannels which interfere with the subchannel of interest. A reception portion provided for each subchannel computes, as a soft decision value, the probability that data received from the subchannel of interest is “0” and the probability that the data is “1”, taking into account the degree of coupling between channels, and moreover uses the soft decision values input from the two upper and lower adjacent reception devices to adjust and output the soft decision value for the subchannel of interest, and based on the adjusted soft decision value, decides whether the received data is “0” or “1”.

摘要： C-HPA separates an input signal into separated signals, and amplifies and combines the separated signals. The C-HPA includes a plurality of signal splitters, a delay discrepancy estimator, and a delay discrepancy adjuster. Each of the signal splitters splits each of the separated signals into a signal in which a time component of the separated signal is put ahead a predetermined time and a signal in which the time component is delayed the predetermined time, and outputs split signals. The delay discrepancy estimator uses the input signal, the split signals output from each of the signal splitters and the combined output signal to estimate delay discrepancy between the separated signals. The delay discrepancy adjuster uses the estimated delay discrepancy to adjust the delay discrepancy between the separated signals.
