  2. 2. Interference Cancellation for DS/CDMA Systems in Flat Fading Channels

    Detta är en avhandling från Chalmers University of Technology

    Författare :Ann-Louise Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Telecommunication; direct-sequence code division multiple access DS CDMA ; multiple data rates; interference cancellation; mixed modulation; parallel channels; multicode; multiuser detection.;

    Sammanfattning : This thesis investigates interference cancellation in direct-sequence code division multiple access (DS/CDMA) systems that support multiple data rates. Two approaches for implementing multiple data rates are considered. One is the use of mixed modulation. The second is the use of parallel channels. LÄS MER
