Patent number: 6580703Abstract: A code reader reads code specification information stored in a code list. An interference level measurer measures the interference level of a received signal despread with the code specification information read by the code reader. A threshold selector selects a code specification information corresponding to an interference level smaller than a preset threshold and stores the selected code specification information in a code candidate list. A code determiner determines the code specification information of a base station from the selected code specification information. When a new base station is added, a base station code may be automatically determined without needing a theoretical design for assigning codes to all base stations.Type: GrantFiled: September 16, 1999Date of Patent: June 17, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiyuki Okubo, Nobuo Asano, Izumi Horikawa

Patent number: 6526271Abstract: A small number of users who provide high interference in the other users, such as a user transmitting a high rate signal, are selected beforehand. First, a signal of the user is demodulated to generate a replica, and a difference between a received signal and the replica is calculated, thereby canceling the interference in signals of the other users, and further improving the system capacity.Type: GrantFiled: October 20, 1999Date of Patent: February 25, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mitsuru Uesugi, Kazuyuki Miya, Osamu Kato, Katsuhiko Hiramatsu, Akinori Tatsumi, Masatoshi Watanabe, Izumi Horikawa, Atsushi Iwaoka

Patent number: 6336040Abstract: A mobile radio system includes a base station and a plurality of mobile radio apparatuses, with each mobile radio apparatus including a control CPU for controlling the mobile radio apparatus and monitoring the state of the hardware of the mobile radio apparatus, a transmitter unit for transmitting data in the form of radio waves, and a CPU monitor unit. The control CPU regularly monitors and checks for any abnormalities in the hardware of the mobile radio apparatus, and the CPU monitor unit regularly monitors and checks for any abnormalities in the control CPU. If there is an abnormality, a disabled transmission out put acceptance signal is supplied to the transmitter unit to inhibit or suppress the output of radio waves thereby avoiding interference to the system caused by unnecessary radio wave transmission from an abnormal mobile radio apparatus.Type: GrantFiled: December 9, 1998Date of Patent: January 1, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Nobuo Asano, Izumi Horikawa

Patent number: 5652752Abstract: In a mobile radio communication system employing a time-division multiple transmission scheme, having a plurality of base stations and a plurality of personal stations, an arbitrary base station, when detecting a pilot signal transmitted from any master base station in the mobile radio communication system, acts as a slave base station which does not transmit its pilot signal but transmits and receives a common control signal to and from a personal station utilizing a frequency channel occupied by the pilot signal. On the other hand, when not receiving the pilot signal, the base station searches for an available frequency channel, and acts as a master base station which transmits its pilot signal on the available frequency channel to occupy the frequency channel, and transmits and receives the common control signal to and from a personal station on that frequency channel.Type: GrantFiled: March 20, 1995Date of Patent: July 29, 1997Assignee: Hitachi, Ltd.Inventors: Toshiro Suzuki, Arata Nakagoshi, Takao Harakawa, Izumi Horikawa, Takakuni Kuki

Patent number: 4710975Abstract: A space diversity reception system which minimizes the inband amplitude and/or phase dispersion by controlling the phase shifter is described. According to the present invention, the interference waves in the two antenna outputs are combined in anti-phase condition. The phase shifter control direction is decided by the sign of the two parameters. One of them is difference between two antenna levels at the center frequency of the pass-band, and the other is the difference of the combined signal levels at the extreme edges of the pass-band. The control means comprises four detectors for detecting said levels, two subtractors for providing said level differences between them, and the control circuit for deciding the phase shifter control direction.Type: GrantFiled: April 5, 1982Date of Patent: December 1, 1987Assignee: Nippon Telegraph & Telephone Public Corp.Inventors: Yoshiharu Okamoto, Izumi Horikawa, Shozo Komaki
