    Abstract : 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. READ MORE

  4. 2. Successive Interference Cancellation in DS-CDMA Systems

    Author : Ann-Louise Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group-wise detection; direct-sequence code division multiple access DS-CDMA ; multiuser detection; multirate schemes; weighted cancellation; successive interference cancellation;

    Abstract : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. READ MORE
