    • 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 ...

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

      Babaroglu, Huseyin; Anttila, Lauri; Xu, Guixian; Valkama, Mikko (07 / 2024)
      article
      <p>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 ...
