Abstract
An apparatus includes a transmitter, a receiver and a combining element. The transmitter includes multiple coupling devices coupled to a coaxial network via multiple respective ports, and is configured to transmit multiple transmit signals via the coupling devices, and to receive from the coaxial network via the multiple coupling devices multiple reception signals. The receiver is configured to receive a combined signal of the multiple reception signals, interfered by multiple respective interfering signals that originate from the multiple transmit signals, and to process the combined signal to recover data carried in the reception signals. The combining element, included in at least one of the transmitter and the receiver, is configured to receive the multiple reception signals from the respective couplers, and to generate the combined signal with a suppressed level of the interference signals by setting at least a phase of at least one of the reception signals.
