Abstract
A receiving device includes: a propagation path compensation unit that compensates a signal by using a propagation path characteristic; a power arithmetic section that arithmetically operates power of a signal; a first reciprocal processing section that performs reciprocal processing on power to output a signal; an error arithmetic section that arithmetically operates an error of the compensated signal; a subtractor that subtracts the signal output from the first reciprocal processing section from the error; a second reciprocal processing unit that performs reciprocal processing on the signal output from the subtractor to output a signal; a first multiplier that multiplies the power and the signal output from the second reciprocal processing unit together to output a signal; and a second multiplier that multiplies the signal compensated by the propagation path compensation unit and the signal output from the first multiplier together to output a signal to an adder.
