Abstract
Official abstract text for this publication.
An OFDM reception device including: a first orthogonal transformation unit that orthogonally transforms a signal for a useful symbol duration included in an OFDM signal and outputs a resulting orthogonally transformed signal; a second orthogonal transformation unit that orthogonally transforms a signal for a guard interval duration included in the OFDM signal and outputs a resulting orthogonally transformed signal; a detection unit that detects a wide band carrier frequency error amount according to the signal output from the first orthogonal transformation unit and the signal output from the second orthogonal transformation unit; and a correction unit that corrects a wide band carrier frequency shift of the OFDM symbol according to the wide band carrier frequency error amount detected by the detection unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. An OFDM reception device for receiving an OFDM symbol that includes a signal for a useful symbol duration and a signal for a guard interval duration generated based on the signal for the useful symbol duration, the OFDM reception device comprising: a first orthogonal transformation unit that orthogonally transforms the signal for the useful symbol duration and outputs a resulting orthogonally transformed signal; a second orthogonal transformation uni…
