Patent number: 11493638Abstract: A multipath (MP) carrier phase detector is disclosed that uses phase differences in the output of Early/Prompt/Late (EPL) correlation for MP detection. Embodiments may take coherent integrations of EPL correlator outputs and determine the respective carrier phase of each output. Phase differences can then be computed, and integer cycles and biases can be removed. MP can then be identified if a maximum phase difference of the EPL correlator outputs are determined to be above a certain threshold. According to some embodiments, false positives may be reduced by averaging phases and/or phase differences over a plurality of samples, and/or if a threshold number of consecutive MP detections have been made.Type: GrantFiled: September 28, 2020Date of Patent: November 8, 2022Assignee: QUALCOMM IncorporatedInventors: Dominic Gerard Farmer, Qingwen Zhang

Patent number: 10659921Abstract: Method, mobile device, computer program product, and apparatus for performing Fine Grain Position Data Collection is described. In one aspect a mobile device performs measurement batching of data, for example positioning and AP measurement data. In some aspects, the mobile device processes positioning and AP measurement data in response to a batch trigger. The mobile device may send the processed measurement batch to a server for analysis or processing. A batch trigger may include receiving a positioning fix with high confidence such that the mobile device may backfilter or otherwise correct mobile sensor based positioning data associated with AP measurements. The server may interpret the data from the measurement batches identified from a number of different mobile devices to calculate position of APs within an environment.Type: GrantFiled: September 23, 2016Date of Patent: May 19, 2020Assignee: QUALCOMM IncorporatedInventors: Sai Pradeep Venkatraman, Dominic Gerard Farmer, Aditya Srivastava, Gengsheng Zhang
