Title:
METHOD AND DEVICE FOR ESTIMATING A TIME OF ARRIVAL OF A RADIO SIGNAL
Document Type and Number:
WIPO Patent Application WO/2018/205169
Kind Code:
A1
Abstract:
A method and a device for estimating a time of arrival (ToA) of a radio signal are proposed. The radio signal comprises M subsignals carried on M subcarriers. A number of propagation paths and a time of arrival associated with a first path are estimated. The technique can improve ToA estimation accuracy, especially in a multipath fading channel, and reduce the need for channel information.
