    Abstract: A user client device with a single receive (RX) chain, a first antenna and a second antenna, and a processor that causes the user client device to couple the single RX chain to the first antenna to receive a first data packet on a first channel and determine a first channel state information (CSI) tile of the first channel based on one or more fields in the first data packet, decouple the first antenna from the single RX chain and couple the second antenna to the single RX chain to continue receiving the first data packet on a second channel, determine a second CSI tile of the second channel based on one or more of a portion of the first plurality of fields, aggregate the first CSI tile with the second CSI tile, and generate a CSI matrix based on aggregating the first CSI tile with the second CSI tile.

    Abstract: A device (e.g., an IoT device) includes a first radio, and a memory device accessible to the first radio. The memory device is configured to store a fingerprinting feature for a specific transmitter device. A second radio and a processor are also included. The process is coupled to the first and second radios. The first radio is configured to extract a fingerprinting feature of a first received wireless signal, determine that the extracted feature matches the fingerprinting feature stored in the storage device, and responsive to the determination that the extracted feature matches the feature stored in the storage device, cause the second radio to transition from a lower power state to a higher power state of operation and continue to receive the incoming signal.

    Abstract: One example includes a passive radar receiver system including an RF receiver front-end to receive a wireless source signal and a reflected signal. An antenna switch of the front-end switches a first antenna to a receiver chain during a first time to generate first radar signal data based on a combined wireless signal comprising wireless source signal and the reflected signal, and switches a second antenna to the receiver chain during a second time to generate second radar signal data based on the combined wireless signal. A signal processor generates source signal data associated with the wireless source signal based on the first and second radar signal data and generates reflected signal data associated with the reflected signal based on the first and second radar signal data, and generates target radar data associated with a target based on the source and reflected radar signal data.
