Paid PhD position in underwater communication with hydrophone arrays
Aalto University Acoustics lab has long history of research of utilization of higher-order spherical arrays in airborne sound. Several spatial audio techniques have been developed, many of which have been taken into use widely in the academia and in industry. During last five years the methods have been also transformed to be used also in underwater applications in a project funded by Saab. Several techniques for underwater localization of sources with such arrays have been developed in Aalto. The follow-up project will continue in the field of underwater communications, also in collaboration with Saab.
Underwater communication between man-made devices is a challenging task: radio-frequencies do not propagate in sea water and the acoustic channel is the only available choice. The acoustical channel usually suffers from very low signal-to-noise ratio, and the properties of it also change rapidly in time which is a major problem in signal transmission. In the project, the student would be working in the field of spatial audio implemented with spherical, cylindrical and linear arrays of hydrophones. Using parametric array processing in signal reception should improve tolerance against background noise. In addition, the parametric analysis may potentially give information of the current properties of the acoustic channel, which potentially may lead into more robust methods for signal reception.
The work would be carried out in Aalto Acoustics lab in Espoo, Finland, with visits to Saab premises.
We are seeking for a funded PhD student with MSc from suitable field. The project will have length of max 4-4.5 year. The student should have knowledge in at least some of these fields:
- acoustics
- multichannel signal processing
- spatial audio
- communications
- hydroacoustics
- artificial intelligence
Send a free-form application for the position with CV, transcript of records and possible letters of recommendation by December 10th, 2023 to Ville.Pulkki@aalto.fi.
The project would start in January 2024.
Please contact Prof Ville Pulkki (
Ville.Pulkki@aalto.fi) with any enquiries you may have about the position.
