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:
Signal distribution, signal switching, and signal collection are performed with a simple configuration. An electronic device comprises a transmission unit (108) for transmitting, as a wireless signal, a signal to be transmitted and a reception unit (208) for receiving the wireless signal transmitted from the transmission unit. In the electronic device, a plurality of pairs of wireless signal transmission points in the transmission unit and wireless signal reception points in the reception unit can be formed. Using the pairs of transmission points and reception points make it possible to execute at least either one of signal distribution in which the same signal to be transmitted from a transmission point is transmitted to the multiple reception points and signal switching in which a signal to be transmitted from a transmission point is selectively transmitted to any of the multiple reception points. The signal to be transmitted is transmitted as a wireless signal. In this case, the signal distribution, signal switching, and signal collection are performed in a wireless signal portion. Since a portion where a signal transmission is performed through electric wiring does not interpose the portion where the signal distribution, signal switching, and signal collection are performed, the signal distribution, signal switching, and signal collection can be performed with a simple configuration.

Abstract:
A signal generation unit 107 and a first set value processing unit 7100 are included in a preceding stage of a transmission path connection unit 108 at a transmission side, and a signal generation unit 207 and a second set value processing unit 7200 are included in a subsequent stage of a transmission path connection unit 208 at a receiving side. The signal generation unit 107 or the signal generation unit 207 performs prescribed signal processing based on a set value. The first set value processing unit 7100 inputs a set value, that has been prescribed for the signal generation unit 107, to the signal generation unit 107, and the second set value processing unit 7200 inputs a set value, that has been prescribed for the signal generation unit 207, to the signal generation unit 207. Since the set value is not dynamically changed according to an environment change, or the like, simplification of a parameter operation circuit or reduction of power consumption is realized, and the parameter operation circuit does not unnecessarily operate even when it is used under the state without environment change.
