  1. 6. Real-time services and multihop networks : Delay analysis of a multihop CDMA fixed relay network

    Master-uppsats, KTH/Mikroelektronik och Informationsteknik, IMIT

    Författare :Ivar Gaitan; [2005]
    Nyckelord :multihop; wireless networks; real-time services; delay;

    Sammanfattning : The next generation of cellular networks is expected to carry high speed IP traffic in a packet switched environment in order to accommodate data traffic for a wide range of services. Much research is thus focused on how to increase the transmission rate in cellular networks. LÄS MER

  3. 7. Simulation of a CDMA system based on optical orthogonal codes

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Andreas Karlsson; [2004]
    Nyckelord :Datorteknik; CDMA; FO-CDMA; superimposed; OOC; correlation; cardinality; multiple access; MAI; BER; Matlab; simulation; Datorteknik;

    Sammanfattning : To take advantage of the high speed in an optic fiber, one of the basic concept in fiber optic communication is to allow several users to simultaneously transmit data over the channel. One technique that provides multiple access is it fiber optic-code division multiple access (FO-CDMA). LÄS MER

  4. 8. Performance Evaluation of Power Control Algorithms in Cellular Radio Communication Systems

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Bala Satish Appuni; Vamsi Krishna Vemasani; [2004]
    Nyckelord :Power Control; CIR; SIR; CDMA; GSM;

    Sammanfattning : Radio resources in wireless communication systems, implementing different multiple access techniques, must be wisely managed. This perspective is pivotal since the variations in propagation channel are very fast and the system is highly complex due to random and unpredictable movement of mobile users continuously. LÄS MER

  5. 9. Design of CMOS RF-Switches for a Multi-Band Radio Front-End

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Anders Hedberg; [2003]
    Nyckelord :Electronics; Switch; CMOS; RF; front-end; radio; SoC; Elektronik;

    Sammanfattning : A study has been made in CMOS RF-switches that can be used in the front-end of a multi-band radio targeting the 802.11a,b,g and W-CDMA standards and working in the frequency range 2.4-5.5GHz. LÄS MER
