Doing the AGC control which adjusts expansion

摘要

Doing the AGC control which adjusts expansion profit with discontinuous profit value it detects the distortion of the plural standard subcarriers which are included in the OFDM signal which is administered fast Fourier transform level of the OFDM signal in the receiving device which it receives uniformly, systematically respectively, presuming the distortion of the OFDM signal which it occurs with the interpolation which uses the particular distortion which is detected, with transmission line propagation it has the equalization section which does the equalization processing which it corrects it causes the equalization section, with the discontinuous expansion profit change of the OFDM signal, it revises presumption error of the distortion of the OFDM signal, making use of the AGC control signal.
