Abstract
Official abstract text for this publication.
An object of the present invention is to provide a receiving apparatus and a receiving method capable of preventing phase rotation of a signal after FFT from occurring on a frequency domain. Further, the receiving apparatus according to the present invention is provided with: a window control unit configured to control a position of an FFT window in which FFT is performed to the time domain signal, and output FFT data corresponding to the FFT window; a signal delaying unit configured to generate, from the time domain signal, a plurality of delay signals with different delay amounts; and a signal switching unit having a switch for outputting by switching between two of the time domain signal and the plurality of delay signals based on a predetermined switch timing, the signal switching unit being configured to output the FFT data including the output signal of the switch.
First claim
Opening claim text (preview).
The invention claimed is: 1. A receiving apparatus for receiving an orthogonal frequency division multiplexing (OFDM) modulated signal modulated based on an OFDM method, and generating decoded data obtained by decoding the OFDM modulated signal, the apparatus comprising: a quadrature demodulator that receives a signal obtained by converting said OFDM modulated signal into a predetermined frequency band, and performs quadrature demodulation on a time domain of said OFDM modulated s…
