摘要: A radio communication system for a communication between a base station and a mobile terminal. The radio communication system repeats a signal transmitted from the base station at repeaters that are multistage-connected by a leaky coaxial cable. Each repeater converts a frequency of an input signal into a different frequency and outputs the frequency-converted signal to the leaky coaxial cable connected to the repeater. The repeaters are provided between the leaky coaxial cables connected in series.

摘要: A charging system for use in a network composed of wireless terminals with a repeater function. As each terminal with a repeater function receives a communication session start request from a user terminal, it searches for a destination user terminal; when it finds the destination user terminal, it transfers the signal sent from the requesting user terminal to the destination user terminal without the mediation of base stations. The information about the amount of data thus transferred or communication time for transferring data is sent to the charging system which is under the control of the communications service provider concerned.

摘要: The wireless LAN system has an information-carrying capacity which is several times the transmission rate obtained by a single cell. The wireless LAN system properly notifies hopping information even if an error in transmission arises. Hopping control is carried out on a master base-station device 10a and slave base-station devices 10b and 10c based on a synchronizing frame generated from hopping timing of the master base-station device 10a. After completion of the hopping control, each base-station device 10 starts to send hopping information to radio terminals 2 present in the same cell. Radio terminals 2, which are in the same cell as one of the base stations 10, work under the base-station device 10.

摘要: An IC card (107) sends its identification code in units of one bit in response to a question from a controller (103). The controller sends back to the IC card the received one bit of the identification code. The IC card compares the received and sent bits. If both are equal, the IC card sends the next one bit to the controller and if not, refrains from sending the next one bit. Thus, even when the number of IC cards which are to be identified and the number of IC cards which send their identification codes are simultaneously large, a reduction in the identification efficiency is suppressed to within a small value.

摘要: The apparatus for manufacturing the fiberboard is in the form of two vertically opposed endless conveyors upon each of which a fiber layer is formed. Each conveyor has a slanted running portion as a part thereof. A suction box is disposed along the inner surface of each of the slanted running portions so that a fiber layer producing section is formed in each slanted portion. A passage is formed between the conveyors to direct a slurry flow of fibers along each conveyor. The relative speeds of the slurry flow through the passage along the surface of the conveyors is adjusted to be different than the running speed of the conveyors; a supply duct for the slurry flow is disposed in the center of said passage and has an outlet near the upper ends of the fiber layer forming sections. The two layers simultaneously formed can be placed upon each other to form a single layer of fiberboard.

摘要: In a wireless communication system in which a sending side derives transmit weight vectors based on feedback information and carries out precoding, performance degradation is caused when the channel at the time when the transmit weight vectors are derived and the true channel are different from each other. Along with variations in the channel, the power allocation to a plurality of effective streams formed in MIMO is caused to approach asymptotically to uniform power allocation from the value determined based on the channel state information that the sending side has.
