Description Communication systems based on non-conventional channels are increasingly used, since they provide an alternative for data transmission in scenarios where traditional wireless or wired channels cannot be used because they are unavailable or ineffective. Applications include, but are not limited to, systems for communication in urban environments, in the post-accident scenario, structural health monitoring and tracking of the operating conditions of an industrial plant. The use of acoustic waves to exchange data through urban water distribution pipelines has emerged as a promising technology, but it presents numerous challenging aspects to the design of the system, such as the small coherence bandwidth of the channel and the low efficiency of the transducers.
The thesis will focus on the optimization of an already launched project, in order to improve its performance.
The main activities will be:
- Preliminary investigation of the modeling techniques for the water-filled pipeline as an acoustical channel.
- Investigation of data modulation/demodulation techniques, suitable for operation with a high bit-rate in noisy and low coherence bandwidth channels.
- Optimization of the performance of an existing prototype.
Required skills - Experience in microcontroller programming (C language).
- Be familiar with basic telecommunication concepts, data modulation schemes, communication channel modeling.
- Familiarity with concepts of acoustic wave propagation is a plus, but not strictly required.
