    University essay from Malmö universitet/Institutionen för datavetenskap och medieteknik (DVMT)

    Author : Mustafa Can Tas; Fatima AlKurdi; [2021]
    Keywords : ;

    Abstract : Digital communication has gone through much development in the past decade. The literature in this field has developed and improved as well, but the educational materials still lack illustrative descriptions. READ MORE

  3. 2. Overcoming Inter-carrier-interference in OFDM System

    University essay from Linköpings universitet/Kommunikationssystem

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

    Abstract : 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. READ MORE

    Abstract : Increasing demand for higher data rates in wireless communication systems has tremendously evolved over the last years. This demand is rapidly increasing with rising in number of wireless devices. READ MORE

  5. 4. Deep Learning for Error Prediction In MIMO-OFDM system With Maximum Likelihood Detector

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Baoqing She; [2018]
    Keywords : MIMO-OFDM; CRC; BLER; Detector; SINR; MCS Selection; Link Adaptation; Deep Learning; Neural Networks;

    Abstract : To increase link throughput in multi-input multi-output (MIMO) orthogonal frequencydivision multiplexing (OFDM) systems, transmission parameters such as code rate andmodulation order are required to be set adaptively. Therefore, block error rate (BLER)becomes a crucial measure which illustrates the quality of the link, thus being used in LinkAdaptation (LA) to determine the transmission parameters. READ MORE
