  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. IOT CONNECTIVITY WITH EDGE COMPUTING

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Maximilian Stiefel; [2018]
    Nyckelord :;

    Sammanfattning : Billions of Internet of Things (IoT) devices will be connected in the next decades. Most devices are for Massive Machine Type Communication (MMTC) applications. This requires the IoT infrastructure to be extremely efficient and scalable (like today’s Internet) to support more and more devices connected to the network over time. LÄS MER

  4. 3. Implementation of 64-point FFTs as a building block for OFDM-based standards with respect to different criteria

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

    Författare :Sarojanarayanamurthy Rajavari Krishnaih Lokanadhan; [2013]
    Nyckelord :;

    Sammanfattning : Abstract This master thesis implements a critical block: Fast Fourier Transform (FFT)/Inverse Fast Fourier Transform (IFFT) for standards using Orthogonal Frequency Division Multiplexing (OFDM). They are used in OFDM systems for modulating / demodulating subcarriers. LÄS MER

  5. 4. Application-aware Scheduling in Multichannel Wireless Networks with Power Control

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Minh Duc Nguyen; [2012]
    Nyckelord :scheduling algorithm; channel-assignment and workload-based;

    Sammanfattning : Scheduling algorithm is the algorithm to allocate system resources among processes and data flows. Joint channel-assignment and workload-based (CAWS) is a recently developed algorithm for scheduling in the downlink of multi-channel wireless systems, such as OFDM. LÄS MER

  7. 5. Design of a DVB-T Receiver : For SFN on a DSP-Processor

    Master-uppsats, Datorteknik; Tekniska högskolan

    Författare :Erik Hägglund; [2012]
    Nyckelord :OFDM; DVB-T; SFN; DSP; Long Delay Spread; Strong Echo;

    Sammanfattning : The goal of this thesis was to implement a DVB-T receiver on Coresonic’s DSP-processor and attempt to evaluate how to design a receiver that is robust against very strong echoes with a long delay. Long delayed echoes is very common in Single Frequency Networks (SFN) which is why focus was put on finding algorithms that work well in SFN. LÄS MER
