  1. 1. 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

  3. 2. PERFORMANCE EVALUATION OF LTE DOWNLINK WITH MIMO TECHNIQUES

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mengistu GESSESE; Olayinka OLADELE; [2010]
    Keywords : 3GPP LTE; 16QAM; 64QAM; EPS; ITU-B; MIMO; OFDM; OFDMA; SCFDMA; SSD; UMTS; ZF;

    Abstract : Long Term Evolution (LTE) of the Universal Mobile Telecommunication System (UMTS) also known as the Evolved Packet System (EPS) is a transilient move in the field of mobile communications. Such a revolution is necessitated by the unceasing increase in demand for high speed connections on networks, low latency and delay, low error rates and resilience because modern users and network applications have become increasingly dependent on these requirements for efficient functionality and performance.

  4. 3. Development of a MATLAB Simulation Environment for Vehicle-to-Vehicle and Infrastructure Communication Based on IEEE 802.11p

    University essay from Institutionen för teknik och byggd miljö

    Author : Samaneh Shooshtary; [2008]
    Keywords : IEEE 802.11p; Vehicle-to-Vehicle communications; MATLAB Simulink; WinProp; WLAN;

    Abstract : This thesis describes the simulation of the proposed IEEE 802.11p Physical layer (PHY). A MATLAB simulation is carried out in order to analyze baseband processing of the transceiver. Orthogonal Frequency Division Multiplexing (OFDM) is applied in this project according to the IEEE 802. READ MORE

  5. 4. Modeling and Prediction of Radio Channels for Orthogonal Frequency Division Multiplexing

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Per-Ola Larsson; [2005]
    Keywords : Technology and Engineering;

    Abstract : In a wireless communication system, the channel is ever changing due to multipath properties such as excess delays and constructive and destructive interference. In a step to optimize system performance, it would be beneficial to have access to channel state information of both present subchannels' future development and subchannels outside the currently used frequency interval.
