1. A method for mapping a structure, the method comprising:
- detecting a plurality of wireless signals that comprise multipath signals that have each experienced at least one reflection against a portion of a structure prior to the detection;
analyzing the plurality of wireless signals to estimate reflection points for the multipath signals;
discriminating single-reflection multipath signals from multiple-reflection multipath signals so as to discriminate true reflection points from false reflection points; and
generating a map of a floor plan of at least the portion of the structure based on the true reflection points.

Abstract
Systems and methods for mapping a structure detect wireless signals, including at least one multipath signal that has experienced at least one reflection against a portion of the structure prior to the detection. The wireless signals are analyzed to estimate reflection points for the multipath signal(s), and a map of at least the portion of the structure is generated based on the estimated reflection points.

17. A system for mapping a structure, the system comprising:
-
a) at least one receiver for detecting a plurality of wireless signals originating from one or more sources, the plurality of wireless signals comprising multipath signals that have each experienced at least one reflection against a portion of a structure prior to the detection; and b) a processor, associated with the at least one receiver, for; i) analyzing the plurality of wireless signals to estimate reflection points for the multipath signals; ii) discriminating single-reflection multipath signals from multiple-reflection multipath signals so as to discriminate true reflection points from false reflection points; and iii) generating a map of a floor plan of at least the portion of the structure based on the true reflection points. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
