System and Method for Combined Performing of Wireless Communication and Sensing
Systems and methods for performing both wireless communications and wireless sensing in combination are disclosed herein. In one example embodiment, the system includes a base station (BS) including each of at least one antenna device including a first antenna device and at least one control unit. The control unit includes an input port coupled at least indirectly to the first antenna device, an output port, and a controllable circuit including each of a spillover cancellation circuit and a bypass circuit.

Method and Technique of Highly Accurate Carrier Frequency Offset Estimation
A wireless communication system (100) estimates a carrier frequency offset between wireless devices (101, 102) by configuring the devices through exchanging packet configuration packets (121, 125) to specify a carrier frequency offset fingerprint (CFOF) sequence in a measurement packet (133, 136) which is transmitted between the wireless devices, where the CFOF sequence in the measurement packet includes a prefix component (31), one or more signature segments (32), and a suffix component (33) for performing CFO measurements at the wireless devices which each process IQ samples corresponding to the signature segments in the received measurement packet by correlating the IQ samples against a reference vector to generate, for each of the one or more signature segments, a carrier frequency offset estimate between the first and second wireless devices.
