Abstract: An electronic device may include communications circuitry, sensing circuitry, and a set of antennas having first and second feeds for covering different polarizations. The communications circuitry may transmit signals with a first polarization using each of the antennas and may concurrently transmit signals with a second polarization using all but a selected one of the antennas. The sensing circuitry may concurrently transmit sensing signals with the first polarization using one of the antennas and may receive sensing signals with the second polarization using the selected antenna. The sensing signals may include chirp signals generated to include muted periods that correspond to a range of frequencies that overlap frequencies at which the wireless circuitry is subject to radio-frequency interference. This may allow for concurrent wireless communications and sensing operations without interference between the communications circuitry and the sensing circuitry.

Abstract: Systems and methods are provided for use of common mode rejection (CMR) for echo cancellation in uplink communications. A node in a cable network configured for transmitting downstream (DS) signals and receiving upstream (US) signals, may include echo cancelling circuits configured for cancelling echo introduced by the DS signals and/or transmittal of the DS signals, onto US signals and/or US reception path, to facilitate full-duplex (FDX) communications of the DS signals and US signal. The echo cancelling circuits may be configured for operating in the analog domain. The echo cancelling circuits may include an echo cancelling combiner configured for combining two or more upstream signals non-coherently.

Radio frequency integrated circuits (RFICs) may be used in phased array antennas to enable configuring large number of phase shifters in highly efficient manner, and to do so in optimal manner, such as with low noise.

Abstract: The present disclosure is directed to a modular and scalable front-end architecture for a massive MIMO communication device, such as a base station. The front-end architecture can allow for the number of antennas at the communication device to be increased or decreased in a simple and cost efficient manner. The front-end architecture can also allow for the number of data streams that can be transmitted and/or received by the communication device to be increased or decreased in a simple and cost efficient manner.

Abstract: A transceiver is disclosed which includes a transmitter and a receiver. The transmitter provides an impairment measurement signal, which is substantially similar to a transmitted communication signal except for a possible difference in phase and/or a magnitude, to the receiver. An envelope detector within the receiver provides an envelope of the impairment measurement signal to the transmitter. The transmitter determines sets of one or more filtering coefficients using the envelope of the impairment measurement signal and adjusts phases or magnitudes and/or phases of a sequences of bits used to generate the transmitted communication signal in accordance with the sets of one or more filtering coefficients to compensate for the unwanted distortion and/or the unwanted interference present within the transmitted communication signal.
