  5. 4. 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
