Latest Patents

Among Ohta's latest patents is an innovative spread spectrum communication device and communication system. This invention introduces a structure that effectively resolves challenges associated with conventional spectrum spreading communication techniques, such as those utilizing Barker codes. By employing a code sequence with a length of at least 14, Ohta’s device limits the rise of the side-lobe of a correctional signal, independently from the order of information codes. The communication device leverages a pseudo-noise code, ensuring a self-correlation side-lobe of no greater than 3. This capability significantly reduces the error rate and enhances the processing gain of the device, even when the pseudo-noise code length exceeds 14.
