Indoor Positioning System for Standards-Based Narrowband mobile Radios Using Spectrally Overlapping Transmissions

Two or more data packets transmitted through a wireless channel are received using a receiver device. The two or more data packets are a result of two or more transmissions that are made sequentially in time at different center frequencies in order to span a desired bandwidth. Each data packet of th...

More Information
Summary:Two or more data packets transmitted through a wireless channel are received using a receiver device. The two or more data packets are a result of two or more transmissions that are made sequentially in time at different center frequencies in order to span a desired bandwidth. Each data packet of the two or more data packets is transmitted at a single center frequency. Time differences and/or carrier phase differences among the two or more transmissions are estimated. A time-of-arrival of one or more data packets of the two or more data packets is calculated using each data packet of the two or more data packets and one or more of the estimated time differences, the different center frequencies, and the estimated carrier phase differences.
