      <p>By the introduction of the fifth generation (5G) mobile communication networks and its physical layer entitled as new radio (NR), the question of link performance in coexistence scenario between the 5G NR and ...

    • 5G new radio uplink performance: Noise, interference and emission constraints 

      Levanen, Toni; Ranta-Aho, Karri; Kaikkonen, Jorma; Nielsen, Sari; Pajukoski, Kari; Renfors, Markku; Valkama, Mikko (08.06.2018)
      conference
      <p>This paper investigates the 5G new radio (NR) uplink (UL) performance with CP-OFDM and DFT-s-OFDM based waveforms. The effects of highly non-linear PA behavior, inter-allocation interference, and UL multi-user ...
