Latest Patents

One of Kohki Shibahara's latest patents is a signal separating apparatus and signal separating method. This invention involves a signal receiving apparatus that includes at least one signal separating apparatus designed to isolate a specific signal from multiple received signals. The apparatus features a spatial filtering unit that separates at least one equalized signal and a decision signal outputting unit that generates a first decision signal based on the equalized signal. The spatial filtering unit utilizes predetermined weighting coefficients to separate the equalized signal by multiplying the received signals with either the first decision signal or a second decision signal from another signal separating apparatus.

Another notable patent is the optically amplified repeater system and optical amplifier. This system comprises optical transmission paths, a multi-channel optical amplifier, and one or more Raman amplification pumping light sources. The multi-channel optical amplifier is equipped with K simultaneous pumping light sources and N optical amplification media, allowing it to amplify the light intensities of optical signals that traverse the optical transmission paths. The Raman amplification pumping light enhances the light intensities of the optical signals, ensuring efficient signal propagation.
