1. 1. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

   University essay from Uppsala universitet/Signaler och System

   Author : Richard Hedlund; [2019]
   Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

   Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.

3. 2. IOT CONNECTIVITY WITH EDGE COMPUTING

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Maximilian Stiefel; [2018]
   Keywords : ;

   Abstract : Billions of Internet of Things (IoT) devices will be connected in the next decades. Most devices are for Massive Machine Type Communication (MMTC) applications. This requires the IoT infrastructure to be extremely efficient and scalable (like today’s Internet) to support more and more devices connected to the network over time. READ MORE

4. 3. 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

5. 4. Performance evaluation and optimization of an OMAP platform for embedded SDR systems

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Carlo Rinaldi; [2011]
   Keywords : ;

   Abstract : During recent years, waveform signal processing within a radio system is performed more and more in the digital domain rather than the analog domain. This is exemplified in Software Defined Radios (SDRs) systems. A SDR is a radio system whose components are realized in software rather than in hardware. READ MORE

6. 5. Spectrum Optimization in Cognitive Radio Networks using Genetic Algorithms

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Adnan Azam; Taimoor Siddique; [2010]
   Keywords : EM; FCC; CR; QoS; GA; SDR; EC; GP; DSP; FPGA; BER; RF; FM; BPSK; QPSK; GMSK; 16 QAM; DPSK; MSK; OFDM; OOK; GW; FP; ABS; AWS;

   Abstract : The rapid revolution in wireless communication in past years has increased the demand of radio spectrum to fulfill quality of service (QoS) requirements of wireless applications, leading to spectrum overcrowding. To solve the spectrum overcrowding problem, cognitive radio (CR) has emerged as a leading technology because it can intelligently sense an unused spectrum without creating any harm to authorized users.
