  1. 1. Overcoming Inter-carrier-interference in OFDM System

    Magister-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Fukang Guo; Luoan Lu; [2021]
    Nyckelord :ICI; OFDM; TDCP; FDCE; Windowing-OFDM; 5G;

    Sammanfattning : This master thesis aims for Inter-carrier interference (ICI) mitigation in orthogonal frequency division multiplexing (OFDM) system by considering designs of frequency domain cyclic extension(FDCE) and optimal windowing pulse shape. Although OFDM system has been put forward in the 1970s, it has just emerged in 4G. LÄS MER

  3. 2. Passive Inter-modulation Cancellation in FDD System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Fan Chen; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Passive inter-modulation (PIM) shows up when two or more RF signals are mixed together via the nonlinear passive devices. With the rapid development and expansion of the wireless com-munication networks, PIM is recognized as one of the most critical issues. LÄS MER

  4. 3. Improvement for LDPC Coded OFDM Communication System over Power Line

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Wu Dan; [2013]
    Nyckelord :low‐voltage power line communication LV‐PLC ; LDPC; OFDM; impulse noise suppression; Class‐A noise;

    Sammanfattning : Power line communication has been around in past decades and gained renewed attention thanks to the demand of high-speed Internet access. With the significant advantages of existing infrastructure and accessibility to even remote areas, power grid has become one of the promising competitors for multi-media transmission in household.

  5. 4. LTE UPLINK MODELLING AND ANALYSIS OF CARRIER FREQUENCY OFFSET ON UPLINK TRANSMISSION INTERFERENCE

    Master-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Johnson Baby; [2013]
    Nyckelord :LTE uplink modelling; Carrier frequency offset on LTE uplink;

    Sammanfattning : This master thesis analyzes the effect of Carrier Frequency Offsets (CFO) on LTEuplink transmission, which is the main cause of ICI (Inter Carrier Interference) andMAI (Multiuser Access Interference). A model of the LTE uplink is required toconduct the study and is implemented in MATLAB, in compliance with 3GPPspecifications. LÄS MER

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

    Master-uppsats, KTH/Signalbehandling

    Författare :Hisham El-Shaer; [2012]
    Nyckelord :;

    Sammanfattning : 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.
