Exploiting Radio Propagation Reciprocity in Wireless Networks

This proposal details an approach for coupling radio channel propagation models with models of the radio frequency electronics in a transceiver to allow simulation of bi-directional channel estimation in a wireless communication system. The proposed efforts focus on exploiting the reciprocal nature of the electromagnetic propagation to reduce overhead necessary for channel feedback or to enable establishment of shared secret encryption keys. The research examines the impact of non-reciprocal portions of the wireless communication channel on these applications and emphasizes calibration and compensation techniques that can remove the non-reciprocal contributions to allow this exploitation of reciprocal channel characteristics.
