  1. 1. Rise Over Thermal Estimation Algorithm Optimization and Implementation

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Saba Irshad; Purna Chandra Nepal; [2013]
    Keywords : Keywords: Enhanced Uplink E-UL ; Rise-over-Thermal RoT ; Thermal noise power floor; Uplink load; scheduling;

    Abstract : The uplink load for the scheduling of Enhanced-Uplink (E-UL) channels determine the achievable data rate for Wideband Code Division Multiple Access (WCDMA) systems, therefore its accurate measurement carries a prime significance. The uplink load also known as Rise-over-Thermal (RoT), which is the quotient of the Received Total Wideband Power (RTWP) and the Thermal Noise Power floor. READ MORE

  3. 2. Evaluation of Word Length Effects on Multistandard Soft Decision Viterbi Decoding

    University essay from Elektroniksystem

    Author : Ahmed Salim; [2011]
    Keywords : Soft-Decision Viterbi; Tail-biting; Zero-tail; Direct Trace-back; Word Length effects; floating point quantization; BER analysis;

    Abstract : There have been proposals of many parity inducing techniques like Forward ErrorCorrection (FEC) which try to cope the problem of channel induced errors to alarge extent if not completely eradicate. The convolutional codes have been widelyidentified to be very efficient among the known channel coding techniques. READ MORE

  4. 3. Modeling and Characterization of an All-Digital Phase-Locked Loop

    University essay from Institutionen för teknik och naturvetenskap

    Author : Alfred Johnson; Fredrik Andersson; [2010]
    Keywords : ;

    Abstract : The thesis "Modeling and Characterization of an All-Digital PLL" aims to create a behavioral model of an All-Digital Phase-Locked-Loop (ADPLL). The model should be able to perform accurate and time-effective simulations. Based on the model, a sub-block requirement will be presented as decision basis for test chip manufacturing. READ MORE

  5. 4. A COMPARATIVE STUDY OF UMTS/WCDMA AND WIMAX TECHNOLOGIES

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : ARIF HUSSAIN; MUHAMMAD-UMAIR ASLAM; SALA HUDDIN; [2009]
    Keywords : UMTS; WCDMA; WIMAX; OFDMA; SER;

    Abstract : The field of mobile broadband in wireless communication systems is increasingly facing the challenges of the provision of high data rates, improved seamless connectivity and broadband internet services. UMTS/WCDMDA which is a third generation wireless mobile cellular technology has been adopted in most parts of the world and now undergoing a phase of evolution and will be emerged soon as LTE.

  6. 5. Interference Cancellation in a Full duplex System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Thomas Ahlström; Claes Bengtsson; [2008]
    Keywords : Technology and Engineering;

    Abstract : In a full duplex system as WCDMA a mobile phone transmits and receives at the same time, but at different frequencies. The transmitted signal will cause interference in the receiver which must be suppressed to not get degraded sensitivity in the receiver. READ MORE
