  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. Receiver Design for Vehicular Communications

    University essay from KTH/Kommunikationsteori

    Author : Olivier Christian Goubet; [2013]
    Keywords : ;

    Abstract : As the mobility of people increases, so does the density of vehicles on road networks. This comes at a cost, causing traffic congestions and raising the number of casualties. Wire- less communications  between vehicles will enable the development of Intelligent Transport Systems (ITS), which are expected to assist and manage road transportation. READ MORE

  3. 3. Multiantenna Time Of Arrival Estimation

    University essay from KTH/Signalbehandling

    Author : Ferran Torrent Fontbona; [2011]
    Keywords : ;

    Abstract : In the communications literature exist many documents that explain how to use spatial diversity to improve the performance of the system. However, the use of spatial diversity has not been studied in depth for GNSS, although in the last years the subject has received some interest, [6] and [20]. READ MORE

  4. 4. Low Complexity Channel Estimation for OFDM Systems Based on LS and MMSE Estimators’

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Md. Jobayer Alam; Shaha Mohammed Goni Abed Sujan; [2010]
    Keywords : Channel Estimation; OFDM; LS Estimator; MMSE Estimator; SLS estimator; Complexity calculation;

    Abstract : In this paper we investigate the block-type pilot channel estimation for orthogonal frequency-division multiplexing (OFDM) systems. The estimation is based on the minimum mean square error (MMSE) estimator and the least square (LS) estimator. We derive the MMSE and LS estimators’ architecture and investigate their performances.
