1. 31. Antenna Characterization with Autonomous UAV and Software Defined Radio

   University essay from Uppsala universitet/Signaler och System

   Author : Lucas Wennerholm; Adam Alenius; [2018]
   Keywords : Signal processing; Software Defined Radio; antenna theory; radio; DSP; Signalbehandling; radio; antenner; antenn; antennteori; SDR; mjukvarudefinierad radio;

   Abstract : A measurement equipment with the purpose of measuring the radiation pattern of antennas in the frequency interval 30-300 MHz was constructed. To perform the necessary measurements the equipment needs to be mounted on a UAV, a necessity that demands a low weight from the measurement equipment. READ MORE

3. 32. Timing delay characterization of GNU Radio based 802.15.4 network using LimeSDR

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Saptarshi Hazra; [2018]
   Keywords : Software Defined Radio; LimeSDR; GNU Radio; Latency; IEEE 802.15.4; USB Transfer Delay; USBMon; Software Defined Radio; LimeSDR ; GNU Radio; Latency ; IEEE 802.15.4; USB Transfer Delay;

   Abstract : Massive deployment of diverse ultra-low power wireless devices necessitates the rapid development of communication protocols. Software Defined Radio (SDR) provides a flexible platform for deploying and evaluating real-world performance of these protocols. But SDR platform based communication systems suffer from high and unpredictable delays. READ MORE

4. 33. Techno-economical analysis of the benefits of anerobic digestion at a rural sisal processing industry in Tanzania

   University essay from KTH/Energisystemanalys

   Author : Cristina Varela González; [2017]
   Keywords : Sustainable development; Tanzania; rural electrification; sisal; CHP; anaerobic digestion; biogas; Hållbar utveckling; Tanzania; landsbygdens elektrifiering; sisal; kraftvärme; anaerobisk rötning; biogas;

   Abstract : The low electrification rates and lack of access to energy services are some of the main challenges of the Tanzanian energy system. However, increasing access to power and other energy services would lead to an increase in the energy demand, which the Tanzanian energy system will not be able to meet. READ MORE

5. 34. Wireless wave propagation in city street canyons

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Andrés Felipe Garcia Albarracin; [2017]
   Keywords : Channel modeling; Channel sounding; Local scattering function; Ray tracing.; Technology and Engineering;

   Abstract : This project aims to determine the characteristics of a wireless communication channel in city-street-canyon scenarios. The channel of a typical city intersection is modeled with a ray tracer and measured with a channel sounder. Then, the results of both tools are compared in terms of the local scattering function.

6. 35. SDR Implementation for Satellite Communication

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Carin Jakobsson; Olof Sjödin; [2017]
   Keywords : ;

   Abstract : SDR (Software Defined Radio) is a radio communicationsystem that has been of great interest and developmentover the last 20 years. It decreases communication costs significantlyas it replaces expensive analogue system components withcheap and flexible digital ones. READ MORE
