  • January 2024: We've submitted the paper "Simple and Fast Decoding of Short LDPC Codes" to ISIT 2024. We are happy and honoured for such a wonderful collaboration with Prof. Carlos Salema. The paper proposes a groundbreaking technique for low-lattency decoding. [Paper].
  • November 2023: By using a duality between error correction and link purification, we have proposed a much more efficient technique for purification of quantum links: Purification-GRAND (PGRAND). Submitted to the high-impact Quantum journal [ArXiv].
  • October 2023: Our Quantum-GRAND (QGRAND) proposal for quantum error correction has just been accepted for publication in IEEE Access [IEEEXplore].

  • July 2023: We have generalised symbol-level GRAND to massive MIMO and proposed using a soft metric to sort the antennas and greatly reduce the decoding time up to 80%. Submitted to IEEE Trans. on Wireless Comms: [ArXiv].

  • April 2023: We have proposed a new metric and a new tool to be used in routing in quantum networks. The proposed metric is based on "fidelity vs entanglement probability" curves. Submitted to Physical Review A: [ArXiv].
  • February 2023: Three journal papers published in their final version in Jan-Feb 2023:
    i) Symbol-level GRAND in IEEE Communications Letters [IEEEXplore];
    and two papers on routing on quantum networks:
    ii) point-to-point entanglement in IEEE Access [
    iii) multipartite entanglement in the Quantum journal [Quantum].
  • September 2022: GRAND decoding over massive MIMO presented and published in VTC-Spring 2022, London [IEEEXplore].
  • August 2022: Decoding any error correction code! A triplet of papers based on noise-centric decoding was just made available:
    i) applying for the first time GRAND in coded massive MIMO and seeing how RLCs outperform 5G's polar codes [ArXiv];
    ii) showing that switching from bit-level GRAND to symbol-level GRAND can reduce computational complexity by half or more [ArXiv];
    iii) extending GRAND to decoding quantum RLCs, with the proposal of Q-GRAND. [ArXiv]
    It was very rewarding to work on these ideas at this stage with co-authors with whom it is a pleasure to work with while exploring ideas in fundamental research.

  • June 2021: Very proud  to seeing our work on MIMO for wireless energy transfer published in the prestigious IEEE Journal of Selected Topics in Signal Processing [IEEEXplore] [ArXiv] [5min video].

  • On sabbatical leave from Feb. 2019 until Feb. 2020, visiting/collaborating with a number of research groups abroad.
  • August 2018: We have successefuly organised ISWCS 2018 in Lisbon (205 participants from all over the world, first-class keynote speakers, state-of-the-art tutorials,...)
