Latest Patents
One of Hisato Kawano's latest patents is a wireless communication device that implements beamforming. This device includes a storage unit, a processor, and a radio circuit. The storage unit holds directivity information that indicates the directivity of radio intensity when beams are formed in multiple main lobe directions. The processor calculates the interference to a first beam from a second beam when instructed to form both beams. The first beam transmits a first signal in a designated main lobe direction, while the second beam transmits a second signal in another direction. Based on the calculated interference, the processor generates a cancellation signal to eliminate the second signal in the first main lobe direction. The radio circuit then transmits both the first signal and the cancellation signal.
Another notable patent is a distortion compensation amplifying apparatus designed for networks using code division multiplex access. This apparatus allows for quick responses to carry out distortion compensation with high accuracy, even when the input signal power varies rapidly. The renewal of a distortion compensation coefficient is complemented based on the amplification results from an amplifier concerning a signal that is code-division-multiplexed in a pseudo-signal multiplexing unit.
