RECEIVER, SIGNAL PROCESSOR, SIGNAL PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To solve such a problem that there is a need for a receiver capable of obtaining a soft decision value for achieving an excellent decoding performance with a small number of signals and a low throughput.

SOLUTION: The receiver comprises: a reception unit receiving an OFDM symbol subjected to primary modulation by a phase shift modulation system; an FFT processing unit acquiring a sub-carrier signal by performing FFT processing on an OFDM symbol thus received; a demapping unit generating a bit string by demapping the sub-carrier signal; a norm calculation unit calculating the norm of the sub-carrier signal; a weighting coefficient generation unit generating the weighting coefficients by taking the statistics of norms thus calculated; and a weighting unit determining a soft decision value by weighting the bit string after demapping by using the weighting coefficients.
