In one example, an integrated relay distributed antenna system includes a relay node communicatively coupled to a base station and a master unit communicatively coupled to the relay node. The relay node is configured to communicate with the base station via a backhaul interface. The master unit is configured to communicate with the relay via an access interface, and the master unit and the relay node are configured to communicate demodulated and decoded data and/or demodulated data with each other. The integrated relay distributed antenna system further includes one or more remote antenna units communicatively coupled to the master unit and located remote from the master unit, wherein the one or more remote antenna units are configured to provide radio frequency signals to a coverage zone via one or more antennas.

An automotive Ethernet physical-layer (PHY) transceiver includes an analog Front End (FE) and a digital processor. The FE is configured to receive an analog Ethernet signal over a physical Ethernet link while the Ethernet PHY transceiver is operating in a vehicle, and to convert the received analog Ethernet signal into a digital signal. The digital processor is configured to hold one or more noise profiles that characterize respective predefined noise types of noise signals that are expected to corrupt the received analog Ethernet signal, to classify an actual noise signal present in the digital signal into one of the noise types, using the noise profiles, and in response to deciding that the actual noise signal matches a given noise type among the predefined noise types, to apply a noise mitigation operation selected responsively to the given noise type.

In some examples, a system includes a receiver configured to receive signals encoding first, second, and third messages in first, second, and third frequency bands. The system also includes a mixer configured to down-convert the received signals to intermediate-frequency (IF) signals based on a local oscillator signal. The system further includes at least one analog-to-digital converter configured to sample the IF signals at a sampling rate. A frequency band of the IF signals encoding the first message falls within a first Nyquist region, and a frequency band of the IF signals encoding the second message falls within a second Nyquist region. The first and second Nyquist regions are frequency ranges bounded by multiples of one-half of the sampling rate, and the second Nyquist region is different from the first Nyquist region. The system includes processing circuitry configured to determine data in the first, second, and third messages based on an output of the at least one analog-to-digital converter.
