Abstract:
Disclosed herein is a wireless transmission system, including: a plurality of systems of millimeter wave signal transmission lines capable of individually transmitting information in a millimeter waveband independently of each other; a sending section disposed on one end side of each of the plural systems of millimeter wave signal transmission lines; and a reception section disposed on the other end side of each of the plural systems of millimeter wave signal transmission lines. The sending section is adapted to convert a signal of an object of transmission into a millimeter wave signal and supply the millimeter wave signal to the millimeter signal transmission line. The reception section is adapted to receive the millimeter wave signal transmitted thereto through the millimeter wave signal transmission line and convert the received millimeter wave signal into the signal of the object of transmission.
Abstract:
PROBLEM TO BE SOLVED: To simultaneously transmit a plurality of signals at a high speed, and with large capacity by wireless among signal transmission devices and inside a device. SOLUTION: A first communication device 100A converts a base band signal into millimeter waves by a signal generating unit 107 and couples the millimeter waves to a millimeter-wave signal transmission line 9 by a transmission line coupling part 108. A second communication device 200A receives the millimeter-waves transmitted via the millimeter-wave signal transmission line 9 by a transmission line coupling part 208, coupled to the millimeter wave signal transmission line 9, and returns the millimeter waves to the base band signal by a signal generation part 207. The millimeter-wave signal transmission line 9 prepares a plurality of systems. When the millimeter-wave signal transmission line 9 has N systems to N types of base band signals, what is required is merely to apply time division multiplex and frequency division multiplex, regarding transmission/reception for performing bidirectional transmission/reception. When there are N types of signals for communication in a millimeter-wave band, they can also be transmitted by each millimeter-wave signal transmission line 9 of 2N systems, even if multiplexing, such as the time division multiplex, frequency division multiplex and code division multiplexing is not performed.
