Title:
VEHICLE-MOUNTED WIRELESS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/090685
Kind Code:
A1
Abstract:
The purpose of the present invention is for the number of transmission lines to be reduced in a vehicle-mounted wireless system that corresponds to a plurality of communication schemes. A first set has a plurality of first antennas and a first receiver. A second set has a plurality of second antennas and a second receiver. Any of the first antennas outputs a first signal that conforms to a first communication scheme. Any of the second antennas outputs a second signal that conforms to a second communication scheme. The first receiver receives, using a diversity scheme, the first signals that are individually outputted by the antennas. The second receiver receives, using a diversity scheme, the second signals that are individually outputted by the second antennas. A multiplexer imparts, to a transmission line, a multiplexed signal that is obtained by multiplexing the first and second signals. A demultiplexer imparts the first and second signals obtained by demultiplexing the multiplexed signal to the first and second receivers, respectively.
