2. 1. Aspects on Interference and Diversity in Wireless Networks

   Author : Fredrik Florén; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; feedback; multiuser communication; diversity; throughput; packet radio networks; Interference; frequency hop communication;

   Abstract : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. READ MORE

4. 2. Antennas and Propagation from a Signal Processing Perspective

   Author : Thomas Svantesson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diversity reception; parameter estimation; higher order modes; mutual coupling; sensor array processing; switched parasitic antennas; physical modeling; channel modeling; MIMO channels; channel capacity;

   Abstract : This thesis studies several topics within the area of antennas and propagation from a signal processing perspective. However, theory and methods from electromagnetics and communications have also been used, contributing to an interdisciplinary character of the thesis. READ MORE

6. 4. Space-Time Algorithms for Mobile Communications

   Author : Per Pelin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna array; model order selection; equalization; Bootstrap; space-time propagation; synchronization; RAKE-combiner; real data; data reduction; spatial diversity; finite alphabet;

   Abstract : Algorithms are presented for space-time signal processing in mobile communication systems employing base station antenna arrays. Two main issues are concerned. Reception of data transmitted on the uplink (mobile to base station transmission), and estimation of the parameters of the space-time mobile channel. READ MORE

7. 5. Study of Multi-Radio Transmission Diversity in Heterogeneous Access Networks

   Author : Georgios Koudouridis; Gunnar Karlsson; Cigdem Sengul; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : With the advent of multi-radio access (MRA), an integration of differentradio access technologies (RATs) into a heterogeneous radio access network(RAN) becomes feasible. Such integration allows a user to be at any instantof time served by one or multiple radio accesses (RAs) concurrently, where anRA constitutes an independent radio resource, such as a carrier or a channel,implemented by a single RAT.
