Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The device may receive a signal on each of N channels from another device. The N channels may include a first channel. The device may determine a frequency response of each of the N channels based on the received signals. The device may transform, from a frequency domain to a time domain, the N frequency responses in order to generate a transformed signal. The frequency response of an nth channel of the N channels may be adjusted by a channel offset of the nth channel with respect to the first channel for n being each integer from 2 to N. The device may then estimate the channel offset for each of the N channels other than the first channel based on the transformed signal.

Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

Abstract: Apparatus and method are provided for estimating the shortest time of arrival or the shortest round-trip time (RTT) of radio signals between communication devices in a wireless network. Filtering is performed by adaptive filters with suppressed side lobes adjustable in the time domain and widths of main lobes adjustable in the frequency domain to improve detection of signals on the shortest path of arrival or line-of-sight (LOS) path while mitigating the effects signals received from longer paths of arrival or non-line-of-sight (NLOS) paths.

Abstract: A method of determining a position of a mobile platform includes obtaining a plurality of pseudorange measurements from multiple time epochs of a satellite navigation system (SPS) and obtaining a plurality of visual-inertial odometry (VIO) velocity measurements from a VIO system. Each time epoch of the SPS includes at least one pseudorange measurement corresponding to a first satellite and at least one pseudorange measurement corresponding to a second satellite. The method also includes combining the plurality of pseudorange measurements with the plurality of VIO velocity measurements to identify one or more outlier pseudorange measurements in the plurality of pseudorange measurements. The one or more outlier pseudorange measurements are then discarded from the plurality of pseudorange measurements to generate a remaining plurality of pseudorange measurements. The position of the mobile platform is then computed based on the remaining plurality of pseudorange measurements and the plurality of VIO velocity measurements.
