Latest Patents
One of Sakamoto's latest patents is a communication system using orthogonal frequency division multiplexed signals. This invention includes an orthogonal frequency division multiplexed signal generator that comprises several components. These components include a data sequence conversion means, a power changing means, an inverse discrete Fourier transform part, and an orthogonal modulation means. The system modulates two independent data streams into an orthogonal frequency division multiplexed signal. The data sequence conversion means arranges the first data to be transmitted in a predetermined order corresponding to multiple orthogonal sub-carriers. The power changing means adjusts the powers of these sub-carriers based on the second data, which is independent of the first. The inverse discrete Fourier transform part generates a time-base waveform by synthesizing the individual sub-carriers. Finally, the orthogonal modulation means performs modulation on real and imaginary axis signals that are orthogonal to each other.
