Agnieszka Czapiewska

Agnieszka Czapiewska is an Assistant Professor at the Department of Radiocommunication Systems and Networks within the Faculty of Electronics Telecommunications and Informatics at Gdańsk University of Technology. Her research focuses on wireless communications in challenging environments, particularly underwater hydroacoustic channels and indoor localization systems.

Her primary research interests include:

• Radiolocalisation and indoor localization techniques
• Underwater wireless communications and hydroacoustic channel characteristics
• Doppler effect mitigation in mobile communication systems
• Multipath propagation analysis and compensation
• Signal processing for wireless communications
• Modulation techniques for challenging communication environments

Dr. Czapiewska's recent publications demonstrate a strong focus on underwater communication challenges, particularly addressing the Doppler effect and multipath propagation in hydroacoustic channels. Her work spans from theoretical analysis of channel characteristics to practical implementation of communication systems for Autonomous Underwater Vehicles (AUVs) and Underwater Sensor Networks (USNs). She has also explored the application of terrestrial IoT technologies like NB-IoT and LTE for maritime communication systems, bridging the gap between established wireless technologies and specialized underwater communication needs.

Her scientific contributions include:

• Development of Doppler shift determination methods for MBFSK modulation
• Comparison of Doppler effect estimation techniques for MFSK transmission
• Analysis of multipath propagation effects in hydroacoustic channels
• Methods for underwater wireless data transmission under non-line-of-sight conditions
• Application of cepstrum filtration to reduce multipath effects

Dr. Czapiewska has been actively involved in several research projects:

• KODEŚ: Power data concentrator with innovative decision functionality for AMI, SCADA, HAN, and IoT environments (2020-present)
• VCS-MLAT: Innovative method of locating aircraft in distributed VCS systems (2017-2023)
• AEGIS: Mobile Device for Generating Electromagnetic Curtain (2016-2019)
