Title:
Receiving set
Document Type and Number:
Japanese Patent JP6028572
Kind Code:
B2
Abstract:
A reception apparatus includes: a Fourier transform unit to output a converted signal; a propagation path estimation unit to calculate propagation-path-estimated-values based on pilot subcarriers; and a propagation path compensation unit, including a filter, to compensate propagation path distortion, the filter includes: first multipliers to multiply the propagation-path-estimated-values of taps other than a center tap by filtering coefficients; a first adder to add outputs of the first multipliers; a first subtractor to calculate an error between an output of the first adder and a propagation-path-estimated-value of the center tap; a filtering coefficient generation unit to generate the filtering coefficients based on the error; a second multiplier to multiply the propagation-path-estimated-value of the center tap by first coefficient; a third multiplier to multiply the output of the first adder by second coefficient; and a second adder to add an output of the second multiplier and an output of the third multiplier.
