Method for estimating distance between transmitter and receiver, and transmitter and receiver implementing same

摘要

Method for estimating the distance between a transmitter and a receiver, the transmitter having radio transmission circuitry adapted for transmitting communication signals within a first bandwidth, the method comprising the steps of: (a) transmitting a ranging signal by means of part of the radio transmission circuitry from the transmitter to the receiver, the ranging signal having a second bandwidth encompassing and exceeding the first bandwith, and (b)estimating the distance from the ranging signal. The invention further relates to a suitable transmitter and receiver for implementing the method.
