Theoretical and experimental analyses on location/channel parameters estimation for implantable medical devices

A maximum a posteriori (MAP) method to simultaneously estimate location and channel parameters for implantable medical devices is proposed. Achievable localisation accuracy is investigated and discussed based on theoretical and experimental evaluation. As for the theoretical analysis, the Cramer–Rao lower bound for the proposed MAP estimation is derived. Consequently, it is demonstrated that the proposed method achieves precious location estimation accuracy from both theoretical and experimental aspects.
