2. 1. Diversity and Interference Aspects in the Downlink of Code Division Multiple Access Systems

   Author : Anders Persson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; orthogonal frequency division multiplexing; multi-carrier modulation; Rayleigh-fading channels; code division multiple access; frequency-selective channels; multiple access interference; diversity;

   Abstract : This thesis consists of six included papers and technical reports, plus an introduction. The topic studied is interference and diversity aspects in code division multiple access (CDMA) systems for mobile cellular communications. The focus in the papers is on the downlink - the communication link from the base station to the mobile terminal. READ MORE

5. 3. Multiuser diversity orthogonal frequency division multiple access systems

   Author : Patrick Svedman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : Multiuser diversity can be used to significantly increase system throughput in wireless communication systems. The idea is to schedule users when they experience good channel conditions and let them wait when the channels are weak. In this thesis, several aspects on multiuser diversity OFDMA systems are investigated. READ MORE

6. 4. From Orthogonal to Non-orthogonal Multiple Access : Energy- and Spectrum-Efficient Resource Allocation

   Author : Lei Lei; Di Yuan; Angelakis Angelakis; Erik Bergfeldt; Xiaoli Chu; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The rapid pace of innovations in information and communication technology (ICT) industry over the past decade has greatly improved people’s mobile communication experience. This, in turn, has escalated exponential growth in the number of connected mobile devices and data traffic volume in wireless networks. READ MORE

7. 5. Medium access control for vehicular ad hoc networks

   Author : Katrin Sjöberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle-to-vehicle communications; SOTDMA; self-organizing TDMA; cooperative system; C-ITS; V2V; ETSI ITS-G5; traffic safety; ISO CALM M5; STDMA; VANET; IEEE 802.11p; V2X; MAC; CSMA; cooperative ITS; medium access control; WAVE; DSRC; vehicular ad hoc networks; scalability; real-time communications;

   Abstract : Cooperative intelligent transport systems (C-ITS), where vehicles cooperate by exchanging messages wirelessly to avoid, for example, hazardous road traffic situations, receive a great deal of attention throughout the world currently. Many C-ITS applications will utilize the wireless communication technology IEEE 802. READ MORE
