  1. 1. Filter Bank Multi-Carrier Modulation

    Uppsats för yrkesexamina på avancerad nivå, KTH/Kommunikationsteori

    Författare :Frédéric De Poret; [2015]
    Nyckelord :;

    Sammanfattning : During the last years, multi-carrier modulations have raised a particular interest due to their high spectral efficiency and the possible assumption of flat frequency fading. The most broadly used multi-carrier modulation is the CP-OFDM. LÄS MER

  3. 2. Iterative Channel Estimation in LTE Uplink

    Master-uppsats, KTH/Kommunikationsteori

    Författare :Erik Lindén; [2014]
    Nyckelord :;

    Sammanfattning : An algorithm for iterative channel estimation using soft feedback for LTE uplink is proposed. The algorithm has low complexity compared to MMSE estimation and does not require knowledge of the channel statistics. LÄS MER

  4. 3. MIMO Channel Equalization and Symbol Detection using Multilayer Neural Network

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Athar Waseem; A.H.M Sadath Hossain; [2013]
    Nyckelord :MIMO; ISI; NN; SER; Channel Equalizer; QAM;

    Sammanfattning : In recent years Multiple Input Multiple Output (MIMO) systems have been employed in wireless communication systems to reach the goals of high data rate. A MIMO use multiple antennas at both transmitting and receiving ends. These antennas communicate with each other on the same frequency band and help in linearly increasing the channel capacity.

  5. 4. Implementation Aspects of 3GPP TD-LTE

    Master-uppsats, Institutionen för systemteknik

    Författare :Ningning Guo; [2009]
    Nyckelord :3GPP LTE; FDD; TDD; OFDM; SC-FDMA; MIMO; FFT; IFFT; SDR;

    Sammanfattning : 3GPP LTE (Long Term Evolution) is a project of the Third Generation Partnership Project to improve the UMTS (Universal Mobile Telecommunications System) mobile phone standard to cope with future technology evolutions. Two duplex schemes FDD and TDD are investigated in this thesis. LÄS MER

  7. 5. Comparison Between WiMAX and 3GPP LTE

    Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Syed Hamid Ali Shah; Mudasar Iqbal; Tassadaq Hussain; [2009]
    Nyckelord :3GPP; LTE; OFDMA; SC-FDMA; SER; WiMAX;

    Sammanfattning : Mobile communication technology evolved rapidly over the last few years due to increasing demands such as accessing Internet services on mobile phones with a better quality of the offered services. In order to fulfil this, wireless telecommunication industry worked hard and defined a new air interface for mobile communications which enhances the overall system performance by increasing the capacity of the system along with improving spectral efficiencies while reducing latencies.
