  2. 1. Uplink Load in CDMA Cellular Radio Systems

    Author : Erik Geijer Lundin; Fredrik Gunnarsson; Oriol Sallent; Linköpings universitet; []
    Keywords : CDMA; Uplink Load; Radio Resource Management; Automatic Control; Cellular Radio; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The uplink of code division multiple access (CDMA) cellular radio systems is often interference limited. The interference originates from many users whose transmission powers are not observable for the system. READ MORE

  4. 2. Coding and Modulation for Wideband CDMA

    Author : Ola Wintzell; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo codes.; Electronics and Electrical technology; channel coding; impulse radio; coordinated transmission; pre-coding; cellular radio capacity; Direct sequence code division multiple access DS-CDMA ; pulse position hopped code division multiple access PPH-CDMA ; Elektronik och elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

    Abstract : Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells.

  6. 4. On interference suppression techniques for communication systems

    Author : Hongxia Zhao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CDMA; QPSK; fixed-point implementation; DQPSK; rapid single flux quantum RSFQ ; MUD; unequal BER; fiber-optic communications; unequal SER; ISI;

    Abstract : The work presented in this thesis concerns interferencesuppression techniques in two different communication systems.In the first part we study fiber-optic systems with practical non-ideal transmitters and receivers, which give rise to intersymbol interference (ISI). READ MORE
