Abstract
Official abstract text for this publication.
A modulator generates a subcarrier modulation signal from an input signal, a parallel-serial converter generates a subcarrier modulation signal from the modulation signal. An IFFT calculator performs reverse Fast Fourier Transform on the subcarrier modulation signal, and a separator separates a calculation result into real part data and imaginary part data. A real part calculator performs a calculation on each element of the real part data to generate real part post-distribution data. An imaginary part calculator performs the data processing on the imaginary part data in the same manner, and generates imaginary part post-distribution data. A combiner combines the real part post-distribution data and the imaginary part post-distribution data to generate a baseband signal, and a transmitter which generates a transmission signal from the baseband signal to transmit generated transmission signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A communication device which communicates with other equipment by wireless communications in accordance with an orthogonal frequency division multiplexing, comprising: a modulator which modulates an input signal, assigns the signal to subcarriers frequency components of which are orthogonal to each other, and generates a subcarrier modulation signal; an IFFT calculator which performs reverse Fast Fourier Transform on the subcarrier modulation signal; a s…
