Clustering with Multiple Receiving Antennas and Imperfect CSI in Downlink CoMP Systems

  • Baracca P.
  • Boccardi F.
  • Prof. Nevio Benvenuto

The impact of inter-cell interference in the downlink can be limited by allowing cooperation among base stations (BSs). Coordinated multi point (CoMP) schemes with joint processing (JP) assumes that BSs share data and channel state information (CSI) to serve the user equipments (UEs) by using joint precoders. By assuming perfect ...
