Remotely powered PPM demodulator by inductive coupling for rodent applications

Catherine Dehollain, Enver Gürhan Kilinç, Franco Maloberti, Kerim Türe

A low-power pulse position modulation (PPM) demodulator has been developed for remotely powered batteryless implantable devices. The required power for the implantable device is provided by the magnetic coupling with the external array of powering of coils ...

Baseband and RF hardware impairments in full-duplex wireless systems: experimental characterisation and suppression

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Andrew Charles Mallory Austin, Pavle Belanovic

Hardware imperfections can significantly reduce the performance of full-duplex wireless systems by introducing non-idealities and random effects that make it challenging to fully suppress self-interference. Previous research has mostly focused on analysing ...

Full-duplex Communication and Remote Powering Implementation of an Electronic Knee Implant

Catherine Dehollain, Oguz Atasoy

Full-duplex communication is realized by using ASK modulation for downlink (the channel from controller to the implant) and by using FSK modulation for uplink (from implant to the controller). The ASK modulation is done at the remote powering frequency and ...
