  1. 21. Energy Ecient Cellular System Design with QoS Assurance

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

    Author : Changyang Zhang; [2014]
    Keywords : ;

    Abstract : Results from the smart-phones' ubiquitous Internet access and diverse multimedia applications, there has been an explosion in mobile data communication, this incredible increase will necessitate continual high energy consumption and leads to more CO2 emissions. It is crucial to develop more energy-efficient systems because of the potential harmful effects to the environment caused by CO2 emissions. READ MORE

    Keywords : Mobile Multhop Relay MMR ; WiMAX; Hard Handover; NCTUns; Base station BS ; Relay station RS ; OFDMA;

    Abstract : Multihop wireless access networks are the subject of much interest at present. In the last few years they have moved from the domain of an interesting research topic to one having a significant impact on the commercial world. READ MORE

  4. 23. Frame Allocation and Scheduling for Relay Networks in the LTE Advanced Standard

    University essay from Kommunikationssystem

    Author : Stefan Roth; [2010]
    Keywords : Relay; Resource Allocation; Scheduling; Weighted Proportional Fairness; LTE Advanced;

    Abstract : The use of relays is seen as a promising way to extend cell coverage and increase rates in LTE Advanced networks. Instead of increasing the number of base stations (BS), relays with lower cost could provide similar gains. READ MORE

  5. 24. User Scheduling Algorithm for MU-MIMO System with limited feedback

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Sudhir Kumar Burra; Reddy Prasad Reddy Yendrapalli; [2010]
    Keywords : MU-MIMO; Bandwidth; Limited feedback; Data rate; Precoder.;

    Abstract : In conventional cellular systems, each base station (BS) transmits signals intended for a single user in a particular resource allocation. As bandwidth is a scarce resource, effective utilization of the available bandwidth in the system is essential in modern wireless systems especially for applications such as video streaming and voice over internet protocol (VoIP) which demands high data rate.

  6. 25. Performance Evaluation of an Uplink Scheduling Algorithm in WiMAX Designing the Adaptive Heuristic Uplink Scheduling Algorithm-AHUS

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Emmanuel Adebomi Oyekanlu; [2009]
    Keywords : Adaptive; Heuristic; WiMAX; Uplink Scheduling; Performance Evaluation; Algorithm;

    Abstract : In this thesis work, the performance of uplink schedulers at the fixed WiMAX MAC layer has been considered. A new algorithm that adapts to changes, inherent in wireless environments, and heuristically optimizes the gains of uplink scheduling parameters has been designed. READ MORE
