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

SLIDE 3

CIFRE PhD

⇒ Acoustic antenna for near ultrasonic MIMO telecommunications Goals: Increase bit rate and control Telecommunication security Multi-user 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)
