RADIO ELECTRIC COMMUNICATION SYSTEM REDUCING INFLUENCE OF MULTI-PATH PHASING

摘要

PROBLEM TO BE SOLVED: To reduce the influence of multi-path phasing while the complicity of a radio terminal and the increase of cost are avoided by transmitting a first signal by means of a first antenna, transmitting a second signal by a second antenna and generating the second signal based on the inversion of the first signal or the alternate non-inversion of it according to schedule. ;SOLUTION: The forward direction channel unit of a base station 500 is provided with a demultiplexer 501, forward direction channel radio equipment 503-1 to 503-c, a forward direction pilot radio equipment 504, an amplifier state 505, an antenna 507-1 and an antenna 507-2. They are mutually connected. A radio exchange center transmits the multiplex data stream of marks containing m-pieces of information transmission signals to the base station 500. The multiplex data stream of the marks is received by the demultiplexer 501, and the data stream is inversely multiplexed. One or more of m-pieces of information transmission signals are transferred to one of c-pieces of forward direction channel radio equipments 503-1 to 503-c.;COPYRIGHT: (C)1999,JPO
