2. 1. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA

   Author : Hongxia Zhao; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). READ MORE

5. 3. 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

6. 4. Stochastic Modeling and Simulation of the TCP protocol

   Author : Jörgen Olsén; Ingemar Kaj; Joachim Charzinski; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; TCP; flow-control; network simulator; ns-2; stochastic modeling; throughput; packet loss rate; fixed-point method; Matematisk statistik; Mathematical statistics; Matematisk statistik;

   Abstract : The success of the current Internet relies to a large extent on a cooperation between the users and the network. The network signals its current state to the users by marking or dropping packets. The users then strive to maximize the sending rate without causing network congestion. READ MORE

7. 5. Object-Oriented Declarative Program Analysis

   Author : Eva Magnusson; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; control; systems; numerical analysis; Declarative object-oriented programming; attribute grammars; fixed-point computations; Computer science; cross references; system; kontroll;

   Abstract : This thesis deals with techniques for raising the programming level for a particular kind of computations, namely those on abstract syntax trees. Such computations are central in many program analysis tools, such as compilers, smart language-sensitive editors, and static analysis tools. READ MORE
