  1. MIMO Telecommunications with Near Ultrasounds Arthur Aubertin 1, 2, 3 , Julien de Rosny 3 , Pierre Jouvelot 2 (1) Stimshop, 14-16 rue Soleillet, 75020 Paris, France (e-mail : arthur@stimshop.com ) (2) MINES ParisTech, Université PSL, Paris, France (3) ESPCI Paris, Université PSL, Institut Langevin Ondes et Images, Paris, France

  2. Context Radio-frequencies telecommunications not always appropriate / allowed ⇒ Ultrasound telecommunications Stimshop (Near-ultrasound) • Industrial : sensor telecommunication / security monitoring • Public : Ultrasonic tags / wireless signature But low bit rate / range

  3. CIFRE PhD ⇒ Acoustic antenna for near ultrasonic MIMO (A.U.) telecommunications Goals: Increase bit rate and control Telecommunication security Multi-user Ultrasonic-telecommunication frame Results: Bit Error Rate model: • Transmission analytical model • Approximate model • Simulation • Impact of chirp-symbol time on BER Experimental prototype: • Channel estimations • Beam Forming / Time Reversal focusing • Multi-users telecommunications (MIMO)
