MIMO can be employed in a distributed manner to enhance coverage and energy efficiency in wireless sensor networks.
Antenna arrays are now part of modern communication standards such as LTE and 5G allowing high bandwidths and low latency. Antenna arrays signal processing can be employed to track direction of arrival of for beamforming onto a receiver.
Radio Based Localization
Localization has become part of daily lives with GPS and apps such as Google Maps. However, for safety of life application GPS is often not reliable enough.
I am really interested in all of these topics, if you fell like we can collaborate feel free to contact me.
