Radio communication device and radio communication method

摘要

A compensator eliminates frequency offset contained in digital-converted signals output from A/D converters. A weighting coefficient calculator, a complex multiplier and an adder eliminate an interference component from a signal from which frequency offset is eliminated. A differential coherent detector demodulates a signal from which the interference component is eliminated. A decoder decodes the demodulated signal, while a frequency offset estimator estimates frequency offset using the demodulated signal and a known symbol.
