1. 1. Full Duplex Multiuser MIMO with Massive Arrays

   University essay from Institutionen för systemteknik; Tekniska högskolan

   Author : Hussain Wannas; [2014]
   Keywords : Full-Duplex; Massive MIMO; MIMO; MU-MIMO;

   Abstract : Half-Duplex Multiuser Multiple-Input Multiple-Output (HD MU-MIMO) systemscurrently employed in communication systems are not experiencing the selfinterference(SI) problem but they are not optimal in terms of efficiency and interms of resources used (time and frequency resources). Ignoring the effect of largescalefading, we start by explaining the uplink (UL) and downlink (DL) parts ofthe MU-MIMO system and how the sum-rate is calculated. READ MORE
