Abstract
A time-reversal wireless system comprising a first wireless transceiver of a time-reversal client, one or more second wireless transceiver and/or a time-reversal client with the first wireless transceiver. The first wireless transceiver of the time-reversal client is wirelessly coupled to the one or more second wireless transceiver through a wireless broadband multipath channel associated with a space. The time-reversal client contains the first wireless transceiver. The time-reversal client also contains a processor and a memory configured to obtain a set of channel state information (CSI) in a channel probing phase, and/or to obtain a set of location-specific signatures based on the set of CSI and/or a time reversal operation in a channel probing phase. The set of CSI is captured when one or more probing signal is sent either from the first wireless transceiver to each of the at least one second wireless transceiver, or from each of the at least one second wireless transceiver to the first wireless transceiver, through the wireless broadband multipath channel associated with the space. A channel passband with bandwidth W0 is associated with the wireless broadband multipath channe…
