One somatotype ecad return estimate canceler and method it uses that the time division duplex communication relay group

摘要

As for this invention, being one somatotype ecad return estimate canceler, order/the automatic profit controller in order to adjust the profit of the opposite direction relay signal, order from the downward look converter outside/detecting the size of phase of the return signal from the forward direction relay signal from the switching section, the automatic profit controller and the switching section in order, the switching to do the opposite direction relay signal the forward direction return signal sensing station in order to renew, detecting the phase and size of the return signal from the opposite direction relay signal from the automatic profit controller and the switching section, the opposite direction return signal sensing station in order to renew, order/The opposite return signal synthetic section in order to form the opposite return signal making use of the phase and size of the return signal from the opposite direction return signal sensing station, removing the order/the return signal from the downward look converter which exists inside the opposite direction relay signal making use of the opposite return signal from the opposite return signal synthetic section, after removing the return signal removal section, and order in order to transmit to the automatic profit controller/the return signal which exists inside the opposite direction relay signal, in order order/to transmit the opposite direction relay signal, it controls each component making use of the synchronization information from the synchronous acquisition section outsideIt has the control section of for the sake of.
