1. 1. Software Defined Radio based MIMO channel sounding

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Jens Elofsson; Peter Seimar; [2016]
   Keywords : channel sounding; MIMO; Zadoff Chu; M-sequences; USRP; FPGA; Technology and Engineering;

   Abstract : With todays increased use of smartphones and other wireless devices, the demands on the wireless networks have increased dramatically. This has prompted the re- search and development of new types of wireless systems using multiple antennas at both the transmitter and the receiver, known as MIMO. READ MORE

3. 2. Pattern Reconfigurable MIMO Antennas for Multiband LTE Operation

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Rui Ma; Ioannis Chountalas; [2015]
   Keywords : Technology and Engineering;

   Abstract : Nowadays, multiple antennas are becoming widely used in small mobile terminals as they can significantly improve wireless communication performance in terms of link reliability and spectral efficiency. Also, pattern reconfiguration is another new trend for antenna design as it enables the antennas to adapt to different propagation and user scenarios. READ MORE

4. 3. Detection and Classification of Interference in Mobile Communication Systems

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Christoffer Ring; [2015]
   Keywords : GSM; Interference; Impulsiveness Ratio; USRP; GNU Radio;

   Abstract : The usage of wireless technology has in the past decade vastly increased and it continues to do so as well. Because of this, we become more and more reliant on this considerably fragile technology. Wireless technology, which uses radio waves to transmit data from one point to another can easily be interfered by radio jammers. READ MORE

5. 4. Ad Hoc Network Nodes Scheduling using DS and FH CDMA

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Farhan Khan; Muhammad Umer Khan and Noman Ellahi; [2013]
   Keywords : Ad Hoc Network; Node Scheduling; FH-CDMA; DS-CDMA;

   Abstract : Nowadays most communication networks like GSM, WLan or WiMAX are based on pre-existing infrastructure. These infrastructures are complicated, costly and difficult to deploy in very short time. Whereas Wireless Ad Hoc Networks are infrastructure-free self organizing networks which consist of co-operating nodes. READ MORE

6. 5. Performance Evaluation of SpectrumSharing between LTE Femtocell andGSM Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Shen Sun; [2012]
   Keywords : ;

   Abstract : In recent years, as the data traffic demand grows rapidly, GSM spectrum refarming is emerging as one cost effective solution for operators to improve its efficiency on spectrum utilization. Among several refarming strategies, a coexistence network where LTE femtocells share the radio spectrum with the existing GSM users is regarded as one with great potential in the future practice.
