  1. 1. Fuzzy Modeling of Uplink Transmit Power Control in a CDMA Network

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Victor Uzoechi; Kenneth Osigwe; [2008]
    Keywords : cellular; channel; co-channel interference; code division multiple access; distributed power control; fast fading; fixed step power control; fuzzy aggregation; fuzzy connectives; fuzzy control; fuzzy operation; fuzzy set; linguistic variable; mobile; multipath; pathloss; power control; proportional-plus-integral control; radio resource management; reuse distance; reverse link; signal-to-interference ratio; slow fading; spread spectrum; target SIR; transmit power control;

    Abstract : From its beginning, transmit power has always placed a significant constraint on the performance of wireless radio systems. The transmit power control problem can be characterized as that of maintaining adequate power in each transmitted waveform so as to increase the expectation that the minimum required SIR at the receiver will at least be reached.

  3. 2. Digital Power Detector for WCDMA Transmitter

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Robert Carlzén; Robert Nilsson; [2008]
    Keywords : Technology and Engineering;

    Abstract : A 3G mobile phone must have the ability to control its output power with high precision. A power detector is used to measure the actual power outputted by the power amplifier to the antenna. With higher data rates the traditional implementations with peak detectors have become very difficult to use, which is why true RMS detectors are needed. READ MORE

  4. 3. Radio Resource Management In 3G UMTS Networks

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Muhammad Abdur Rahman Haider; Abu Bakar Bhatti; Ammar Ahmad Kirmani; [2007]
    Keywords : 3G; UMTS; RRM;

    Abstract : Universal Mobile Telecommunication System (UMTS) is a third generation mobile communication system, designed to support a wide range of applications with different quality of service (QoS) profiles. This 3G system has capability of transporting wideband and high bit rate multimedia services along with traditional cellular telephony services e. READ MORE

  5. 4. 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

  6. 5. 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
