    摘要: A wireless communication system experience interference from other wireless communication networks. A method for designing wireless communication systems subject to interference is proposed based on a realistic interference model which accounts for the propagation effects introduced by the wireless environment (such as path loss, shadowing, and multipath fading), and for the spatial scattering of transmitters (using a Poisson field). The method accounts for tradeoffs between network parameters, such as signal-to-noise ratio (SNR), interference-to-noise ratio (INR), path loss exponent, spatial density of the interferers, and error probability. Advantages of this method include: 1) a unified framework for designing a wireless system, subject to cumulative interference and noise, incorporating a wide range of performance metrics; and 2) a general application that covers a broad class of wireless communication systems and channel fading distributions.

    摘要: A first elapsed time from transmission of a data segment until receipt of an acknowledgement is measured. A probability distribution of the first elapsed time is generated for a client device 50 on the basis of the measured first elapsed time. A second elapsed time from retransmission of a data segment until receipt of an acknowledgement is measured. A probability distribution of the second elapsed time is generated for a client device 50 on the basis of the measured first elapsed time. An estimation is made as to whether an acknowledgment pertains to which data segment on the basis of the generated probability distribution.

    摘要: Plural terminal devices are arranged under a relay apparatus. The relay apparatus includes a mobile communication network connection unit, a packet switching network connection unit, and an emergency call determination unit. The emergency call determination unit determines whether or not the calls originated from the terminal devices are emergency calls, and when the calls are the emergency calls, connects the emergency calls to the mobile communication network connection unit. When the calls are the emergency calls, the mobile communication network connection unit connects the emergency calls to the mobile communication network by issuing thereto a notice on an identification number of the relay apparatus, the identification number being stored in an IC card attached to the relay apparatus.

    摘要: When a connection is established between a client device and a server device, a first message requesting establishment of a downlink connection is transmitted from the client device to the server device, and a server device which has received the first message is caused to transmit to the client device a second message requesting establishment of an uplink connection. The client device which has received the second message is caused to transmit to the server device a third message acknowledging the second message and requesting establishment of the downlink connection. The server device which has received the third message is caused to establish the downlink connection based on the content of the third message.

    摘要: A control apparatus for use with an electric power conversion system which is equipped with a dc/ac converter connected to an electric rotating machine and a capacitor joined to input terminals of the dc/ac converter. The control apparatus stores an angle of rotation (i.e., start angle θ0) of the electric rotating machine before start of control of energization of the electric rotating machine to discharge the capacitor and determines command currents idr and iqr which will result in zero (0) torque in the electric rotating machine. The control apparatus includes a command current correcting circuit which corrects the command currents idr and iqr by a difference between a current angle θ of rotation of the electric rotating machine and the start angle θ0, thereby avoiding constant rotation of the electric rotating machine when the capacitor is discharged.
