  1. 1. Pilot Contamination and Mitigation Techniques in Massive MIMO Systems

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Vidit Saxena; [2014]
    Keywords : Multicell Systems; Massive MIMO; Pilot Contamination; LTE; Power Control; Resource Allocation; Channel Estimation; Precoding; Technology and Engineering;

    Abstract : A multi-antenna base station (BS) can spatially multiplex a few terminals over the same bandwidth, a technique known as multi-user, multiple-input multiple-output (MU-MIMO). A new idea in cellular MU-MIMO is the use of a large excess of BS antennas to serve several single-antenna terminals simultaneously. READ MORE

  2. 2. Evaluation of Particle Swarm Optimization Algorithm for Precoding in Coordinated Multi-Point System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Amir Shehni; [2013]
    Keywords : Index Terms--- Coordinated Multi-Point; Precoding; Particle Swarm Optimization; Stochastic Optimization;

    Abstract : In future communication system, the constraint of recourse allocation are a challenging topic. One way for observing such constraint is to apply frequency reuse factor of one in commu- nication system. Taking this factor to one causes the system to have serious problems such as small sum rate and interference speci cally at cell-edge. READ MORE

  3. 3. Performance Evaluation of SpectrumSharing between LTE Femtocell andGSM Networks

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

    Author : Shen Sun; [2012]
    Keywords : ;

    Abstract : In recent years, as the data traffic demand grows rapidly, GSM spectrum refarming is emerging as one cost effective solution for operators to improve its efficiency on spectrum utilization. Among several refarming strategies, a coexistence network where LTE femtocells share the radio spectrum with the existing GSM users is regarded as one with great potential in the future practice.

  4. 4. A distributed, load-aware, power and frequency bargaining protocol for LTE-based networks

    University essay from Kommunikations- och transportsystem; Tekniska högskolan

    Author : Muhammad Sajid; Imran Siddiqui; [2012]
    Keywords : LTE; OFDMA; FFR; protocol; power allocation; frequency allocation.;

    Abstract : In this thesis a distributed, dynamic, load aware, joint power and frequency allocation protocol for 4G networks along with system-level simulated results are presented. In all cellular networks, a key limiting factor for throughput is inter-cell interference, especially at the cell edges. READ MORE

  5. 5. 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
