Patent number: 8855247Abstract: According to one embodiment, a wireless receiving apparatus includes a receiver, a phase rotation module and a demodulator. The receiver receives a first signal, the first signal being processed a bit conversion, a scramble and an M-phase shift keying modulation processes. The phase rotation module multiplies a first symbol obtained from the first signal with an amount of phase rotation determined by a scramble sequence used for the scramble, to obtain a second symbol. The demodulator demodulates the second symbol by referring to signal points of N-PSK replica signal generated based on a data rate and the bit conversion process and calculates a likelihood obtained from demodulation as a soft decision value.Type: GrantFiled: August 8, 2012Date of Patent: October 7, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Hiroki Mori, Masaki Ogata

Patent number: 7663974Abstract: A fishfinder is provided for identifying with high precision a single fish under the ship and for measuring the length of the fish precisely. An operator of the fishfinder is assisted to grasp the depth and the length of the fish. A fishfinder transmits an ultrasound pulse having a high carrier frequency and an ultrasound pulse having a low carrier frequency by means of a pulse transmission and reception device at predetermined time intervals. A single fish echo is determined and tracked for a plurality of transmission intervals of ultrasound pulses emitted into the water. A target strength of single fish is measured based on the signal strength of a low carrier frequency echo signal from the single fish. The length of the fish is measured based on the target strength. A fish mark is displayed on the screen of an indicator, with the size of the fish mark depending on the fish length.Type: GrantFiled: October 2, 2006Date of Patent: February 16, 2010Assignee: Furuno Electric Company LimitedInventors: Mitsuhiro Inouchi, Toshiyuki Shimizu, Masahiko Mushiake, Masaki Ogata, Yoshito Okubo
