    摘要: A receiver architecture for canceling blocking signals in the receive path includes a low noise amplifier for receiving and amplifying an inbound RF signal to produce an amplified inbound signal, in which the inbound RF signal includes a modulated RF signal and a blocking signal, and a cancellation module for substantially canceling the blocking signal from the amplified inbound RF signal and substantially passing the modulated RF signal. The cancellation module cancels the blocking signal by generating an injection signal representative of the blocking signal, combining the blocking signal with the injection signal to produce an error signal, updating the injection signal based on the error signal and using the injection signal to cancel the blocking signal from the amplified inbound RF signal.

    摘要: An RF transmission system includes a plurality of RF transmitters that generate a plurality of RF signals at a selected carrier frequency in response to a frequency selection signal. A plurality of programmable antennas are each tuned to the selected carrier frequency, in response to the frequency selection signal, to transmit a corresponding one of the plurality of RF signals.
