  4. 3. IP Multicasting over DVB-T/H and eMBMS : Efficient System Spectral Efficiency Schemes for Wireless TV Distributions

    Master-uppsats, Institutionen för informationsteknologi och medier

    Författare :S.M. Hasibur Rahman; [2012]
    Nyckelord :eMBMS; DVB-T; Multicasting; system spectral efficiency;

    Sammanfattning : In today’s DVB-T/H (Digital Video Broadcasting-Terrestrial/Handheld) systems, broadcasting is employed, meaning that TV programs are sent over all transmitters, also where there are no viewers. This is inefficient utilization of spectrum and transmitter equipment. IP multicasting is increasingly used for IP-TV over fixed broadband access. LÄS MER

  5. 4. DAB Transmission System Simulation

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Sammanfattning : DAB (Digital Audio Broadcasting) is the radio digital system developed as an european standard by the ETSI, EN 300 400, based on the Eureka-147 group works, to improve the performance of the analogue radio systems (AM and FM). The system is based on the OFDM technology which allows DAB to exploit the spectrum frequencies in a better way with a higher quality of sound for mobile receivers specially. LÄS MER
