    • Cellular Digital Post-Distortion: Signal Processing Methods and RF Measurements 

      Babaroglu, Huseyin; Anttila, Lauri; Xu, Guixian; Turunen, Matias; Allén, Markus; Valkama, Mikko (2023)
      conference
      <p>In this paper, we study the feasibility of digital post-distortion (DPoD) based mitigation of transmitter nonlinear distortion in cellular networks. With specific emphasis on downlink, we describe a computationally ...

    • Design Considerations of Dedicated and Aerial 5G Networks for Enhanced Positioning Services 

      Del Peral-Rosado, Jose A.; Nolle, Patric; Razavi, Sara M.; Lindmark, Gustav; Shrestha, Deep; Gunnarsson, Fredrik; Kaltenberger, Florian; Sirola, Niilo; Särkkä, Olli; Roström, Juha; Vaarala, Kim; Miettinen, Pasi; Pojani, Giacomo; Canzian, Luca; Babaroglu, Huseyin; Rastorgueva-Foi, Elizaveta; Talvitie, Jukka; Flachs, Detlef
      ESA Workshop on Satellite Navigation Technologies and European Workshop on GNSS Signals and Signal Processing (2022)
      conference
      <p>Dedicated and aerial fifth generation (5G) networks, here called 5G overlay networks, are envisaged to enhance existing positioning services, when combined with global navigation satellite systems (GNSS) and other ...

    • Digital Post-Distortion for DFT-s-OFDM 

      Babaroglu, Huseyin; Anttila, Lauri; Lampu, Vesa; Tervo, Oskari; Tiirola, Esa; Valkama, Mikko
      Asilomar Conference on Signals, Systems, and Computers proceedings (2024)
      conference
      In this paper, we propose and describe a novel digital post-distortion (DPoD) method for enhancing the received signal error vector magnitude (EVM) in discrete Fourier transform spread orthogonal frequency-division ...

    • Digital Post-Distortion for Multi-Layer MIMO-OFDM 

      Babaroglu, Huseyin; Anttila, Lauri; Xu, Guixian; Valkama, Mikko (07 / 2024)
      article
      In this letter, we propose a new digital post-distortion (DPoD) technique for precoded multi-layer orthogonal frequency division multiplexing (OFDM) systems, in order to enhance the received signal error vector magnitude ...

    • Receiver Side Signal Processing for Nonlinear Distortion Compensation in 5G AND Beyond 

      Babaroglu, Huseyin (2023)
      Diplomityö
      Trading between transmit waveform quality and power efficiency is one of the most challenging issues in radio transmitter implementation. To this end, digital predistortion is the de-facto solution for mitigating power ...
