摘要: A means and method to increase the beam traffic capacity, especially in high user density regions, of a multi-beam antenna communication system with multiple signals at any frequency transmitted (received) when transmit (receive) mode by canceling interference neighboring signals. An cancellation network is provided for caused sidelobe(s) least one signal or more other network. Each power divider divides its input into reference fractional non-reference signal. Phase shifters/attenuators shift phase attenuate amplitude combiner combines composite emerging from combiner. The phase/attenuation settings are selected optimize ratio each communications link.
