    摘要: A power correction value generating unit determines a power correction value for minimizing an error, from a reference output power value of a carrier multiplexed signal, generating due to peak power suppression under a carrier setting based on the carrier setting relating to either one or both of the number of carrier signals and frequency arrangement, and peak suppression setting. An output power error correcting unit corrects a signal gain before or after the carrier signals are multiplexed, using the power correction value obtained by the power correction value generating unit. In an apparatus performing peak suppression according to an input limitation power of the power amplifier, it is possible to always obtain a desirable transmission (output) power even when the number of carriers or carrier frequency arrangement varies.

    摘要: A path defining/changing/deleting section sets in advance the definition of the setup of a PVC connection in a PVC connection object management table as a PVC connection object. Each PVC connection object has an attribute indicating an active or inactive state. When a request is made by a reservation controlling section for activating or deactivating an object PVC connection, a PVC active/inactive state controlling section can immediately read from the PVC connection object management table a PVC connection object indicating the definition of the setup of the object PVC connection, to send commands based on the definition to each of network elements (NE) which comprise an information communications network.

    摘要: A method and an apparatus for measuring the strength of an AC electric field or an equivalent voltage, or the strength of an AC magnetic field or an equivalent current, based on a light beam which is transmitted through and thus modulated by an optical sensing head due to the Pockel's and Faraday effects, while the sensing head is exposed to the AC electric and magnetic fields. The sensing head includes an optical material which exhibits the Pockel's effect and an optical material which exhibits the Faraday effect, or includes an optical material which exhibits both the Pockel's and Faraday effects. The modulated beam is applied to a light-sensitive element, which produces an electric output signal. A first and a second component of the electric output signal are retrieved by respective detectors. The first component has a same frequency as that of the electric or magnetic field, while said second component has a frequency which is two times that of said electric or magnetic field. The electric field strength or the voltage, and the magnetic field strength or the current are determined by one and the other of the first and second components, respectively.
