  1. 6. 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

  3. 7. Power Control and Resource Allocation for Device-to-Device Communications in Cellular Networks

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

    Author : Aidilla Pradini; [2013]
    Keywords : ;

    Abstract : Device-to-device (D2D) communications in cellular networks will improve traditional cellular systems in many ways. By allowing user equipment (UE) in proximity to communicate through direct links, the transmitter would be able to transmit with lower power while the receiver could still receive better-quality signals.

  4. 8. Performance Evaluation of Packet Scheduling Algorithms for LTE Downlink

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ömer Arslan; Olufemi Emmanuel Anjorin; [2012]
    Keywords : LTE; 3GPP; OFDMA; Downlink Scheduling; CQI;

    Abstract : Long Term Evolution (LTE) of the Universal Mobile Telecommunications System (UMTS) is designed to revolutionize mobile broadband technology with key considerations of higher data rate, improved power efficiency, low latency and better quality of service. It promises high peak data rates of 100 Mbps downlink and 50 Mbps uplink transmissions and can operate in different bandwidths ranging from 1. READ MORE

  5. 9. Interference Management in LTE-Advanced Heterogeneous Networks Using Almost Blank Subframes

    University essay from KTH/Signalbehandling

    Author : Hisham El-Shaer; [2012]
    Keywords : ;

    Abstract : Long term evolution (LTE) is the standard that the Third-generation Partnership Project (3GPP) developed to be an evolution of UMTS. LTE offers higher throughput and lower latency than UMTS and this is mainly due to the larger spectrum used in LTE but in terms of spectrum efficiency LTE does not offer a lot of improvements compared to UMTS.

  6. 10. 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
