Abstract: A method for aligning visual-inertial odometry (VIO) and satellite positioning system (SPS) reference frames includes obtaining a plurality of range-rate measurements of a mobile platform from an SPS. The range-rate measurements are with respect to a global reference frame of the SPS. The method also includes obtaining a plurality of VIO velocity measurements of the mobile platform from a VIO system. The VIO velocity measurements are with respect to a local reference frame of the VIO system. At least one orientation parameter is then determined to align the local reference frame with the global reference frame based on the range-rate measurements and the VIO velocity measurements.

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: Provided are apparatus and methods for ranging between a plurality of wireless devices. An exemplary method includes, at a first wireless device, transmitting a primary portion symbol comprising a first packet and transmitting a secondary portion symbol. The secondary portion symbol is transmitted simultaneously at a lower transmit power than the primary portion symbol, and the secondary portion symbol comprises a second packet identical to the first packet. The primary portion symbol can be transmitted in a first channel having a substantially 20MHZ bandwidth and the secondary portion can be transmitted in a second channel having a substantially 20MHZ bandwidth. The first and second channels are substantially adjacent in frequency. After transmitting the primary portion symbol, for example, a high-throughput long-training-field symbol or a very-high-throughput long-training-field symbol can be repetitively transmitted. This exemplary method enhances time-of-arrival estimation accuracy, minimizes decoding bottlenecking, and maximizes wireless device range.
