1. An apparatus for providing a tag location of a tag, the apparatus comprising:
an anchor configured to receive a wireless signal from the tag;
a data storage configured to store a set of channel responses; and
a processor communicatively connected to the data storage, the processor being configured to:
determine an estimated channel response based on the received wireless signal; and
estimate the tag location based on the estimated channel response and the set of channel responses;
wherein determination of the estimated channel response includes configuring the processor to perform a matched filtering
operation; and

a matched filter receiver communicatively connected to the processor, the matched filter receiver being configured to:
correlate the received wireless signal;
estimate a set of channel response characteristics associated with the received wireless signal; and
provide the set of channel response characteristics to the processor;
wherein the matched filtering operation is based on the transmitted wireless signal.
