  1. 1. Ad Hoc Network Nodes Scheduling using DS and FH CDMA

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Farhan Khan; Muhammad Umer Khan and Noman Ellahi; [2013]
    Keywords : Ad Hoc Network; Node Scheduling; FH-CDMA; DS-CDMA;

    Abstract : Nowadays most communication networks like GSM, WLan or WiMAX are based on pre-existing infrastructure. These infrastructures are complicated, costly and difficult to deploy in very short time. Whereas Wireless Ad Hoc Networks are infrastructure-free self organizing networks which consist of co-operating nodes. READ MORE

  3. 2. "Characterization of RSSI based Proximity Detection"

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Dinesh Ramesh Kumar; [2013]
    Keywords : Localization technique; Propagation; pathloss; RFID;

    Abstract : Real Time Locating System (RTLS) is a widely used monitoring application that assists in tracking and identifying persons or any objects using Anchors(nodes), RF tags and WSN. This is simplified by using the Chirp Spread Spectrum (CSS) technology . READ MORE

  4. 3. Performance Analysis of Cyclostationary Sensing in Cognitive Radio Networks

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Asif Mirza; Faique Bin Arshad; [2011]
    Keywords : Cyclostationary Sensing in Cognitive Radio; BPSK QPSK Signal detection;

    Abstract : Cognitive radio is one of the modern techniques for wireless communication systems to utilize the unused spread spectrum effectively. This novel paradigm makes wireless communication possible with less interference. In our work we have investigated one of the functions of cogni- tive radio called spectrum sensing. READ MORE

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Muhammad Adnan Khan; Naseer-Ud-Din Shinwari; [2009]
    Keywords : CDMA; TDd-CDMA; Rake Receiver;

    Abstract : The field of telecommunications has made tremendous progress of the past decade, especially in the area of wireless communications. The world becoming a global village due the advancement in the field of wireless communications, the requirement for standardization and uniformity becomes an essential issue. READ MORE

  6. 5. 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.
