1. 11. Low-PAR Precoding for Very-Large Multi-User MIMO Systems

   University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska högskolan

   Author : Christopher Mollén; [2013]
   Keywords : MIMO; PAR Reduction; Precoding; Multi-User; MIMO; toppvärdesreducering; förkodning; fleranvändarförkodning;

   Abstract : Storskaliga fleranvändar-MIMO-system, med hundratals basstationsantenner, studeras med allt större intresse både inom akademin och industrin. En anledning är att sådana system kan betjäna flera enantennsanvändare samtidigt över samma tids-frekvens-resurs med fleranvändarförkodning. READ MORE

3. 12. Linear Precoding Performance of Massive MU-MIMO downlink System

   University essay from Kommunikationssystem; Tekniska högskolan

   Author : Eakkamol Pakdeejit; [2013]
   Keywords : Massive MU-MIMO; Multiuser-MIMO; Linear precoding; Spectral efficiency; Energy efficiency;

   Abstract : Nowadays, multiuser Multiple-In Multiple-Out systems (MU-MIMO) are used in a new generation wireless technologies. Due to that wireless technology improvement is ongoing, the numbers of users and applications increase rapidly. Then, wireless communications need the high data rate and link reliability at the same time. READ MORE

4. 13. Coordinated MIMO Precoder EvaluationBased on Measurement in IndoorEnvironment

   University essay from KTH/Signalbehandling

   Author : Xiaoqian Zhu; [2013]
   Keywords : ;

   Abstract : In this thesis, we investigate the performance of the coordinated MIMO precoders, using measured channels in indoorvenvironment. Instead of simulated radio propagationvconditions, measured channels are used to evaluate the precoder performance for real-world channels. READ MORE

5. 14. Precoding in MIMO, OFDM to reduce PAPR (Peak to Average Power Ratio)

   University essay from Institutionen för datavetenskap, fysik och matematik, DFM

   Author : Muhammad Irfan Ishaq; Yasir Ali Khan; Muhammad Talha Gul; [2012]
   Keywords : Peak to Average Power Ratio;

   Abstract : One of the critical issues of systems utilizing Orthogonal Frequency Division Multiplexing (OFDM) is the high peak to the average power ratio of OFDM signals. We have used Precoding as a way to mitigate the PAPR problem. Furthermore the performance of Precoded OFDM in fading multi-path channels has been studied. READ MORE

6. 15. User Scheduling Algorithm for MU-MIMO System with limited feedback

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Sudhir Kumar Burra; Reddy Prasad Reddy Yendrapalli; [2010]
   Keywords : MU-MIMO; Bandwidth; Limited feedback; Data rate; Precoder.;

   Abstract : In conventional cellular systems, each base station (BS) transmits signals intended for a single user in a particular resource allocation. As bandwidth is a scarce resource, effective utilization of the available bandwidth in the system is essential in modern wireless systems especially for applications such as video streaming and voice over internet protocol (VoIP) which demands high data rate.
