Patent number: 6628611Abstract: In a communication system, a first transfer rate is assigned to a first user terminal requesting a variable-rate mode of transmission and a second transfer rate is subsequently assigned to a second user terminal requesting a constant-rate mode of transmission if the second transfer rate is equal to or smaller than a remaining capacity of the transmission link.

Publication number: 20030152050Abstract: A receiver of a multicarrier communication system capable of reducing inter-subcarrier interfering signals is to be provided. Receive signals received by a receiving antenna are amplified by a receiving amplifier, subjected to quadrature demodulation by multipliers with respect to the respective subcarriers, and band-limited by lowpass filters. The signals band-limited by the lowpass filters are converted into digital signals by A/D converters at a sampling frequency fs. With respect to the receive signals converted into digital signals, interfering signals leaking between subcarriers are estimated by using A/D converted by the A/D converters and are canceled. The receive signals reduced in interfering signals are multiplexed into a single sequence by a multiplexer, and decoded by a decoder into output signals.Type: ApplicationFiled: February 12, 2003Publication date: August 14, 2003Applicant: NEC CorporationInventor: Takashi Mochizuki

Publication number: 20020082038Abstract: During soft handover, base station selector 22 selects the base station that is transmitting the downlink signal with the best downlink reception quality, and notifies the base stations of the ID of this base station, so as to cause only the selected base station to transmit user data. Downlink signal weight decision circuit 23 estimates base stations that have a likelihood of transmitting user data. Downlink TPC command decision circuit 25 uses the downlink signal from the base stations that have a likelihood of transmitting user data, to decide whether the transmission power of the base stations is excessive or insufficient, and to instruct the base stations to increase or decrease their transmission power. Data demodulator 27 uses the downlink signals from base stations that have a likelihood of transmitting user data to demodulate the user data.Type: ApplicationFiled: December 18, 2001Publication date: June 27, 2002Applicant: NEC CORPORATIONInventor: Takashi Mochizuki

Patent number: 6327384Abstract: In a projection means black pixel histograms of a binary stationary image are generated in both the vertical and the horizontal direction. In a text type judgment means, in accordance with these histograms, a determination is made of whether the image is vertical text or horizontal text. Based on the result of this determination, a pattern block extraction means extracts either a column or a row from the image. The block is further projected and divided into smaller blocks. Then projection is again applied to these divided blocks and patterns are extracted by a pattern extraction means. A judgment is made as to whether or not joining of the extracted patterns is to be performed and, if joining is required, they are joined by a pattern joining means and finally the offsets of all the extracted patterns are calculated, whereupon data (of extracted patterns) are sent to a pattern matching process.Type: GrantFiled: November 13, 1997Date of Patent: December 4, 2001Assignee: NEC CorporationInventors: Kouichirou Hirao, Keiji Yamada, Takahiro Hongu, Takashi Mochizuki, Mitsutoshi Arai
