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.

Abstract: A device includes a BLUETOOTH low energy (BLE) link layer (LL) controller configured to maintain a link cluster including multiple links between the device and one or more connected devices that share parameters associated with the link cluster and to process data associated with the links of the link cluster at a LL. The links of the link cluster established according to a BLE communication standard. The device further includes or is coupled to BLE physical link (PHY) interfaces coupled to the BLE LL controller and configured to exchange the data on different links of the link cluster at different respective signal frequencies, interface with the BLE LL controller, and process the data at a PHY layer.

Abstract: A method includes determining to send a data packet from a first transceiver to a second transceiver, the data packet configured according to a TCP, determining, at the first transceiver, to trigger the second transceiver to send an ACK packet according to a delayed ACK protocol, sending, from the first transceiver, the data packet with an additional packet responsive to determining the triggering of the ACK packet, and receiving, at the first transceiver, the ACK packet from the second transceiver responsive to the additional packet.
