ABSTRACT:
A time-division communication system wirelessly receives a communication signal during receive time periods and wirelessly transfers a communication signal during transmit time periods. These communication signals have multiple receive and transmit channels. The communication system circulates the received communication signal to various filters that pass particular receive channels and that reflect other receive channels back the circulator(s). Eventually, the reflected receive channels circulate to the appropriate filters and are passed. The filters also pass transmit channels to the circulator(s) where they are circulated and reflected until they combine into the transmit communication signal.
