Among other things, embodiments of the present disclosure help to overcome environment-specific dependency issues of conventional Wi-Fi-based sensing systems, thus allowing a neural network to make better proximity predictions in an unseen environment. Other embodiments may be described and claimed.

Proximity detection using wi-fi channel state information

The present disclosure relates to methods and apparatuses for compensating carrier or clock signal phase fluctuations. An apparatus comprises a digital phase locked loop () comprising a phase error output () for a phase error () between a reference signal () and an output signal () generated by the digital phase locked loop, and a phase rotator () coupled to the phase error output () and configured to rotate a phase of a data signal based on the phase error ().

Apparatuses and methods for compensating phase fluctuations

Devices and methods of compensating for a bandpass filter are generally described. A DTx includes a BPF from which an output signal is produced and a DFE having a zero crossing (ZC) pre-distorter (ZCPD). The ZCPD compensates for ZC distortion from a desired analog signal caused by the BPF. The ZCPD adjusts a DTC code word to generate a DTx output signal to be applied to the BPF. The compensation is dependent on a magnitude of the square wave immediately prior to and after the ZC. The compensated DTC and a DPA code word are used to generate the DTx output signal. The compensation produced by the ZCPD is free from compensation for non-linear responses to the DTC and DPA code words.

Zero-cross-pre-distortion (ZCPD) algorithm for DTC based polar DTx

A digital polar transmitter arrangement having a digital front end (DFE) and a transmit chain is disclosed. The DFE is configured to resample a baseband signal relative to a carrier frequency at a carrier frequency related sample rate, calculate zero crossing positions of the resampled signal, generate delay to time converter (DTC) commands based on the zero crossing positions, calculate amplitude values for the zero crossing positions and generate dynamic phase alignment (DPA) commands based on the amplitude values. The transmit chain is configured to generate an output signal having amplitude and phase modulation based on the DTC and DPA commands.

Digital polar transmitter having a digital front end

Described herein are technologies related to an implementation for dynamic adjustment of an out-of-band emission in a wireless modem, including spurious emissions, such as a Wi-FI modem, to minimize interference on a collocated or co-running downlink reception of another wireless modem residing on the same device by dynamically adjustment of a power consumption.

Interference mitigation by a scalable digital wireless modem

A system for signal processing is provided. The system includes a steady state processing system for receiving a signal. A general purpose processing system is coupled to the steady state processing system and includes a signal acquisition system for receiving the signal and generating acquisition data. The steady state processing system can receive the acquisition data from the signal acquisition system and use the acquisition data to acquire the signal.
