1. 1. Radio Resource Management in Bunched Personal Communication Systems

   Författare :Miguel Berg; KTH; []
   Nyckelord :radio resource management; dynamic channel allocation; power control; interference avoidance; link-gain matrix; path-loss measurements; microcells; mobile positioning; trilateration;

   Sammanfattning : The traditional way of increasing capacity in a wirelesscommunication system has been cell splitting and fixedchannel-allocation based on prediction tools. However, theplanning complexity increases rapidly with the number of cellsand the method is not suitable for the large temporal andspatial traffic variations expected in the future. LÄS MER

3. 2. Single-User Receivers for Partly Known Interference in Multi-User Environments

   Författare :Bo Hagerman; Jens Zander; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellular systems; mobile radio systems; co-channel interference; inter-cell interference; interference adaptive receiver; macrocells; microcells; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : In multiuser environments such as cellular radio systems, the limited available bandwidth is one of the principal design constraints. For future high subscriber density systems, frequency reuse is one of the fundamental approaches for efficient spectrum utilization in order to meet the increased demands for capacity. LÄS MER
