1. 1. Performance Evaluation of 802.15.4 UWB PHY for High Speed Data Rate under IEEE Channel Mode

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Athanasios Vasileiadis; [2015]
   Nyckelord :Technology and Engineering;

   Sammanfattning : In modern day society the increase of data generation and transfer has been an issue that researchers are working on. This generated and shared data might have a different purpose but one thing is certain, the reception. This communication can cover continents, countries, cities or even just a few meters. LÄS MER

3. 2. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

   Master-uppsats, KTH/Kommunikationssystem, CoS

   Författare :Zhuo Cheng; [2011]
   Nyckelord :WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

   Sammanfattning : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. LÄS MER

5. 4. PERFORMANCE EVALUATION OF RAKE RECEIVERS USING ULTRA WIDEBAND MULTIPATH CHANNELS

   Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Författare :Zain Mian-Zubair; Hashim Safdar; [2008]
   Nyckelord :Ultra Wideband; Rake Receiver; Multipath channel;

   Sammanfattning : In this report, we derive the performance graphs for UWB communication systems using different combining techniques in a RAKE Receiver. Comparisons have also been made between the techniques and conclusions have been drawn based on the requirements. We also incorporate the effect of number of fingers on the performance of the receivers. LÄS MER

7. 5. Modelering av Wideband : Code Division Multiple Access

   Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

   Författare :Jack Huynh; Mattias Gylin; [2005]
   Nyckelord :Datorteknik; CDMA; W-CDMA; TDD; FDD; Rake combining; 3GPP; Rayleigh fading channel; spreading; Datorteknik;

   Sammanfattning : Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. LÄS MER
