• Effective Channel Hardening in an Indoor Multiband Scenario 

      Ghiaasi, Golsa; Abraham, Jens; Eide, Egil; Ekman, Torbjörn (Journal article; Peer reviewed, 2019)
      We evaluate channel hardening for a large scale antenna system by means of indoor channel measurements over four frequency bands, 1.472 GHz, 2.6 GHz, 3.82 GHz and 4.16 GHz. NTNU’s Reconfgurable Radio Network Platform has ...
    • Fast and Accurate Simulation Technique for Large Irregular Arrays 

      Bui Van, Ha; Abraham, Jens; Arts, Michel; Gueuning, Quentin; Raucy, Christopher; González-Ovejero, David; de Lera Acedo, Eloy; Craeye, Christophe (Journal article; Peer reviewed, 2018)
      A fast full-wave simulation technique is presented for the analysis of large irregular planar arrays of identical 3-D metallic antennas. The solution method relies on the macro basis function (MBF) approach and an interpolatory ...
