Patent number: 11050597Abstract: Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.Type: GrantFiled: July 29, 2020Date of Patent: June 29, 2021Assignee: SUN PATENT TRUSTInventors: Yutaka Murakami, Tomohiro Kimura, Mikihiro Ouchi

Patent number: 11043796Abstract: Systems and methods are disclosed to detect cloud-to-ground (CG) strokes that include and/or are followed by continuing current (CC). For example, earth-based lightning data may be generated for one or more lightning pulses detected in an environmental space using multiple earth-based lightning detection sensors. Space-based lightning data may be received for one or more optical signals detected in the environmental space using one or more space-based lightning detection sensors. It may be determined from the earth-based and space-based lightning data whether a lightning pulse is a CG stroke that includes or is followed by CC. Charge transfer of a CG stroke with CC may be obtained from measurements of electromagnetic fields by an array of electromagnetic field sensors to generate training data. A machine learning model may be trained to relate space-based and/or earth-based lightning data to charge transfer where there is no proximate array of electromagnetic field sensors.Type: GrantFiled: May 1, 2020Date of Patent: June 22, 2021Assignee: Vaisala, Inc.Inventors: Martin J.
