  1. 1. Coding, Modulation and Multiuser Decoding for DS-CDMA Systems

    Författare :Tony Ottosson Gadd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The general trend both in wireless and fixed network communication systems is flexibility in services, data rates, desired delay and performance. Future systems should not be designed for specific services but be more general and allow for a multitude of services, both now existing and those not yet invented. LÄS MER

  3. 2. Multirate Schemes and Multiuser Decoding in DS/CDMA Systems

    Författare :Tony Ottosson Gadd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi processing-gain; multi-channel; soft decoding; vector quantization.; joint optimization; Direct-Sequence Code Division Multiple-Access DS CDMA . multirate; multi-modulation; multiuser detection;

    Sammanfattning : Direct-Sequence Code Division Multiple-Access (DS/CDMA) has for some yearsbeen considered as a candidate for future personal and mobile communications.The reasons are mainly the properties of universal frequency reuse andthe multi-path mitigation. LÄS MER
