摘要: A communications system is disclosed for spectrum sharing of a microwave point-to-point and PCS system. The invention comprises This includes transmitter transmitting first signal second signal. the are oppositely circularly polarized electromagnetic waves within predefined frequency range. also receiver receiving signals. In preferred embodiment present may further include It would then combining circuitry to generate composite comparator comparison by comparing average value amplitude with predetermined value. Finally, control circuit responsive modifying operation transmitter.
