    摘要: Examples of a system and method for adaptively tuning a radio frequency (RF) front-end are generally described herein. In some examples, the frequency of a transmit signal of RF front-end circuitry is swept in at least a part of the RF transmit band. RF power in a receiver is detected as a function of the RF frequency of the transmit signal to determine a location of at least one tunable notch or other band stop element in the frequency domain. Information from the detected RF power is determined as a function of the RF frequency of the transmit signal. The RF front-end circuitry is adjusted to a selected frequency response using the determined information.

    摘要: The disclosed invention relates to a transceiver system having one or more receive antennas that receive a first radio frequency (RF) signal and a plurality of transmit antennas that wirelessly transmit a second RF signal. A local channel determination unit provides data corresponding to the environment of local communication channels (i.e., the communication channels between the transmit antennas and the receive antennas) to a beamforming element, which enables beamforming functionality within the transmit and/or receive antennas (e.g., by using analog or digital weights to vary the radiation pattern generated by the transmit antennas) so as to attenuate RF signals extending between the transmit antennas and the receive antennas. By attenuating signals extending between the transmit and the receive antennas, a high degree of isolation is achieved between transmission and reception paths

    摘要: The disclosed invention relates to a MIMO (multiple input, multiple output) wideband transceiver. In some cases, the MIMO wideband transceiver comprises a signal processor that outputs or receives a plurality of distinguishable data streams. A first data stream is provided to a first antenna port connected to a plurality of wideband antennas, while a second data stream is provided to a second antenna port connected to a wideband antenna. A spatial filter element configured to assign antenna weights to the plurality of wideband antennas, which cause the wideband antennas to operate in a manner that attenuates wireless signals, at a frequency range at which the wideband transmit wideband radiate, in the direction of the wideband antenna without attenuating the wireless signals in other directions. By attenuating signals extending between the plurality of wideband antennas and the wideband antenna, wideband decoupling between first and second antenna ports is achieved.
