Abstract: A technique for sensing a moving object within a physical environment
using a MIMO communication link includes generating a channel matrix
based upon channel state information of the MIMO communication link. The
physical environment operates as a communication medium through which
communication signals of the MIMO communication link propagate between a
transmitter and a receiver. A spatial information variable is generated
for the MIMO communication link based on the channel matrix. The spatial
information variable includes spatial information about the moving object
within the physical environment. A signature for the moving object is
generated based on values of the spatial information variable accumulated
over time. The moving object is identified based upon the signature. |
