Statistical Inference for Communications and Positioning (SI)

Introduction

Research activities at the SI Department are focused towards designing advanced receiver techniques and architectures for the new generation of Communication and Positioning systems. The Department carries out fundamental and applied research in the fields of statistical signal processing, communication theory, multi-antenna systems, data fusion, and PHY prototyping. Activities are centered in four main research lines:

  • Advanced synchronization techniques, robust to propagation impairments and weak signal conditions (strong involvement in deep space communications and robust ranging).
  • Coding aspects for (5G and beyond) wireless communications, including (physical-layer) network coding and decoding algorithms.
  • Anywhere/anytime positioning systems, including GNSS and indoor positioning solutions with proof-of-concept developments.
  • Prototyping of PHY communication and positioning systems, with focus on baseband processing but encompassing end-to-end receiver design.
