      Bucher, Stephan; Ragab, Ahmed N.; Yammine, George; Fischer, Robert F.H,; Waldschmidt, Christian (Universität Ulm, 2018-10-15)
      Massive MIMO is one of the key technologies that enables an increase in capacity in multi-user MIMO systems. However, these systems suffer from high channel estimation complexity and its degradation due to pilot contamination. ...
    • Influence of channel parameters on noncoherent massive MIMO systems 

      Beitrag zu einer Konferenz
      Bucher, Stephan; Yammine, George; Fischer, Robert F.H.; Waldschmidt, Christian (Universität Ulm, 2018)
      In multi-user massive MIMO uplink systems, noncoherent detection schemes offer an appealing alternative to classical coherent detection algorithms. Sorted decision-feedback differential detection (DFDD) in combination with ...
