  3. 2. 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

  4. 3. Indoor Location Detection using WLAN

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Anqi Luo; Lei Ge; [2010]
    Nyckelord :WLAN; location detection accuracy; arrival signal and processing;

    Sammanfattning : The thesis seeks to improve the accuracy of indoor wireless local area network (WLAN) location detection. The main task of the project is the design and analysis of a solution, which utilizes the packets which are already emitted by WLAN devices. The system consists of a signal receiver and signal processing. LÄS MER

  5. 4. LiUMIMO : A MIMO Testbed for Broadband Software Defined Radio

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Johan Fältström; Fredrik Gidén; [2009]
    Nyckelord :matlab in the air; mimo; radio forensics; SDR; Software defined radio; LTE; WiMAX; LiUMIMO; FPGA;

    Sammanfattning : In order to keep up with the increasing demand on speed and reliability in modern wireless systems, new standards have to be introduced. By using Multiple Input Multiple Output technology (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) technologies the performance can be increased dramatically. Forthcoming standards such as WLAN 802. LÄS MER

  7. 5. Implementation of an IEEE 802.11a transmitter in VHDL for Altera Stratix II FPGA

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Johannes Brännström; [2006]
    Nyckelord :OFDM; WLAN; 802.11a; VHDL; FPGA;

    Sammanfattning : The fast growth of wireless local area networks today has opened up a whole new market for wireless solutions. Released in 1999, the IEEE 802.11a is a standard for high-speed wireless data transfer that much of modern Wireless Local Area Network technology is based on. This project has been about implementing the transmitter part of the 802. LÄS MER
