  1. 16. Cardinality for optical orthogonal codes with variable length and weight

    University essay from Institutionen för systemteknik

    Author : Erica Isaksson; [2006]
    Keywords : Optical Orthogonal Code; CDMA; Multilength OOC; Multiweight OOC;

    Abstract : To let many users benefit from the high speed communication in an optical fiber, a way to share the channel is needed. One way to share the channel between the users is the multiple access technique of Code Division Multiple Access, CDMA. This technique is based on coding. READ MORE

  3. 17. Real-time services and multihop networks : Delay analysis of a multihop CDMA fixed relay network

    University essay from KTH/Mikroelektronik och Informationsteknik, IMIT

    Author : Ivar Gaitan; [2005]
    Keywords : multihop; wireless networks; real-time services; delay;

    Abstract : The next generation of cellular networks is expected to carry high speed IP traffic in a packet switched environment in order to accommodate data traffic for a wide range of services. Much research is thus focused on how to increase the transmission rate in cellular networks. READ MORE

  4. 18. Cross-layer Optimization of CDMA Multihop Radio Networks

    University essay from KTH/Reglerteknik

    Author : Simone Loretti; [2004]
    Keywords : ;

    Abstract : In this thesis, the problem of finding the jointly Scheduling, Power and Rate allocation for Wireless ad hoc networks is considered. The motivation for this study is limiting multiuser interference in order to increase the total utility, throughput, and spatial reuse of the system. READ MORE

  5. 19. Performance Evaluation of Power Control Algorithms in Cellular Radio Communication Systems

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Author : Bala Satish Appuni; Vamsi Krishna Vemasani; [2004]
    Keywords : Power Control; CIR; SIR; CDMA; GSM;

    Abstract : Radio resources in wireless communication systems, implementing different multiple access techniques, must be wisely managed. This perspective is pivotal since the variations in propagation channel are very fast and the system is highly complex due to random and unpredictable movement of mobile users continuously.

  6. 20. A distributed, mobile positioning systemfor wireless, handheld devices

    University essay from KTH/Teleinformatik

    Author : Fredrik Christiansson; [2000]
    Keywords : Location awareness; positioning; mobile devices; wireless; handheld; fares; Bluetooth; time difference of arrival; TDOA; synchronization; timing; network; picocell;

    Abstract : This thesis investigates the possibilities of implementing a location awareness mechanism for the so-called lesswire localNavigator. The author claims that it is possible to implement such a mechanism within the given prerequisites and constraints, even though with today’s technology it may not be economically feasible. READ MORE
