1. 1. Robust MIMO Precoding on Real-World Measured Channels

   Master-uppsats, KTH/Signalbehandling

   Författare :Filip Hedenskog; [2015]
   Nyckelord :MIMO; maximin; imperfect CSIT; real-world measured channels; uncertainty set; worst-case robustness;

   Sammanfattning : It is well known that multi-input multi-output (MIMO) wireless communication systemsthat employ precoding techniques are capable of meeting the high expectations of modernand future wireless communication standards. In order to fully utilize these techniques, thecommunication system typically requires information of the channel, commonly referred toas channel state information (CSI). LÄS MER

3. 2. Coordinated MIMO Precoder EvaluationBased on Measurement in IndoorEnvironment

   Master-uppsats, KTH/Signalbehandling

   Författare :Xiaoqian Zhu; [2013]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

4. 3. A Mote-in-the-Loop Approach for Exploring Communication Strategies for Sensor Networks

   Master-uppsats, Institutionen för informationsteknologi

   Författare :Minyan Hong; [2010]
   Nyckelord :;

   Sammanfattning : A wireless sensor network (WSN) consists of a number of electronic devices called sensor nodes, which are capable of sensing, computation and wireless communication. The variable properties of wireless communication links make robust and fault-tolerance sensor communication an interesting topic. LÄS MER
