1. 31. 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. 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.
