Title: Satellite communication system
IPC: H04W74/04
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To reduce interference between same frequencies without the need for complicated control by storing a pattern of directivity and assigning a different pattern to a base station from that of an adjacent base station using the same frequency. SOLUTION: A base station with a plurality of directivity decision patterns selects a 1st directivity decision pattern among the plurality of directivity decision patterns. Another base station adjacent to the base station selects a different directivity decision pattern from the 1st directivity decision pattern. Then a remote base station uses repetitively the 1st directivity decision pattern so as to avoid the adjacent base station to use the same antenna directivity at the same time. For example, frame timings of base stations b1-b17 using the same frequency are synchronous with each other, each base station has a directivity antenna having a sector horizontal plane directivity and a plurality of sector antennas cover a zone around the respective base stations.

IPC: G06F11/00
Filed: 1989-12-01
Abstract: PURPOSE:To surely detect fault by fixing the output of an output transistor TR circuit of a bus or a fault flag line to the low level at the time when the bus or the fault flag line is in the trouble mode and detecting disaccord between transmission data from the external and the output of a receiver to output the detection signal.
