发明名称 SYSTEM AND METHOD FOR HIGH RESOLUTION INDOOR POSITIONING USING A NARROWBAND RF TRANSCEIVER
摘要 A sequence of two or more signals representing two or more data packets is transmitted through a wireless channel using a transmitter device. The two or more signals 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. At least one of the two or more signals includes a physical layer preamble. The sequence of two or more signals is received using a receiver device. A time of arrival of one or more signals of the received sequence is calculated using one or more of the received sequence, the time differences among the two or more transmissions, the different center frequencies, information from the two or more data packets, and any carrier phase differences among the two or more transmissions using the receiver device.
