  1. 31. Interference Management for Heterogeneous Networks in 3GPP LTE Advanced and Beyond

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

    Author : Asif Ali Khan; [2011]
    Keywords : ;

    Abstract : The primary goals of the thesis study were to evaluate the Closed Subscriber Group (CSG) based Heterogeneous Network (HetNet) deployments and identify the impact of CSG LPN cells on various system performance metrics (cell throughput, UE throughput and interference levels etc.) in contrast to the case when Open Access (OA) LPN cells are deployed in the macro cell area.

  3. 32. Analysis of Interference and Performance in Heterogeneously Deployed LTE systems

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

    Author : Mattias Bergström; [2011]
    Keywords : ;

    Abstract : Heterogeneous network deployment has been advocated as a mean to enhance the performance of cellular networks, but at the same time heterogeneous deployments give rise to new interference scenarios which are not seen in homogeneous deployments. This report includes five studies pertaining heterogeneous network deployments which is based on simulations of LTE in high detail on the lower layer protocol stack. READ MORE

  4. 33. Simulation and Optimization of Frequency Reuse in OFDMA Networks

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Azeem Waqar; Muhammad Ammar Zafar; [2011]
    Keywords : ;

    Abstract : Efficient radio resource management is an important aspect when it comes to achieving high bit rates in technologies such as the 3GPP Long Term Evolution (LTE). This thesis aims at understanding existing frequency reuse schemes in OFDMA networks, and to develop an algorithm for frequency allocation for irregular cellular layouts. READ MORE

  5. 34. Design and Implementation of as Asymmetric Doherty Power Amplifier at 2.65 GHz in GaN HEMT Technology

    University essay from Elektroniska komponenter; Tekniska högskolan

    Author : Mohsin Mumtaz Tarar; [2011]
    Keywords : Asymmetric Doherty Power amplifier;

    Abstract : Power amplifiers are an indispensible part of the wireless communication systems. Conventional PAs provide peak efficiency at peak output power which is obtained at a certain fixed optimum resistance. These kind of amplifiers are normally called switched-mode power amplifiers (SMPAs) and are used for constant envelope signals. READ MORE

  6. 35. Smart Antenna - MIMO, OFDM and Single Carrier FDMA for LTE.

    University essay from Linnéuniversitetet/Institutionen för datavetenskap, fysik och matematik, DFM
