  1. 1. Investigating new Service System Solutions for High Altitude Balloons : Feasibility Study and Design Challenges

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Joakim Peterson; [2016]
    Keywords : High altitude balloon; service system; corona discharge;

    Abstract : The high altitude balloon operations at Esrange Space Center have been goingon since 1972, and about 550 launches have been performed. Their present service system for the high altitude balloons is about 18 years old. To be able to meet the requests from their customers, SSC have started the development of a new service system.

  3. 2. 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.

  4. 3. Algorithms for analysis of GSM phones’ modulation quality

    University essay from Institutionen för systemteknik

    Author : Tobias Carlstedt; [2009]
    Keywords : GMSK; algorithms; frequency error; phase error; output power;

    Abstract : Instruments for analyzing radio signals are very expensive and their full capacity is seldom used outside the research and development and the type approval departments. Instrument manufacturers have historically integrated the hardware and the software into a single unit. But some instrument manufacturers are beginning to change this. READ MORE

  5. 4. Decision Making Techniques for Cognitive Radios

    University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Abstract : Spectrum scarcity is one of the biggest challenges that the modern world is facing. The efficient use of available licensed spectrum is becoming more and more critical with increasing demand and usage of the radio spectrum. READ MORE

  6. 5. Design and implementation of an SDR receiver for the VHF band

    University essay from Institutionen för systemteknik

    Author : Emad Athari; Petter Lerenius; [2007]
    Keywords : SDR; software-defined radio; radio; GMSK; receiver; FPGA;

    Abstract : The purpose of this thesis work is to examine the possibility of building a software-defined radio (SDR) for the VHF-band. The goal is to accomplish this with as few components as possible, thus cutting down the size and the production cost. An SDR solution means that the sampling of the signal is done as close to the antenna as possible. READ MORE
