  1. 21. Digital Predistortion for Broadcast FM repeaters

    University essay from KTH/Signalbehandling

    Author : Manne Tallmarken; [2011]
    Keywords : ;

    Abstract : This thesis presents the design and implementation of a memoryless and adaptive digital predistorter used to linearize a power amplier. Specically, it deals with the implementation of a so-called constantgain predistorter, based on a lookup table, on a digital signal processing board built around an FPGA. READ MORE

  3. 22. Analyzing and implementation of compression algorithms in an FPGA

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Markus Janis; [2011]
    Keywords : ;

    Abstract : The thesis is performed at ÅF AB in Stockholm. One of the development projects needed a compression algorithm. The work has been done in two major stages. Background theory was compiled and evaluated with respect to the suitability for FPGA implementation. READ MORE

  4. 23. Observer Implementation in an FPGA Using Simulink and Xilinx System Generator

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Omer Farooq; Bodiuzzaman Molla; [2010]
    Keywords : State observer; Hamiltonian Modelling; Stability of observer; FPGA;

    Abstract : In order to reduce the cost of the current switched resonant power converters, a state observer is introduced to provide the controller with the required information for the effective switching of the converter without the need of expensive sensory inputs from the resonant circuit. This Master's thesis investigates the usage of Matlab/Simulink and Xilinx System Generator as an implementation tool for Field Programmable Gate Array (FPGA) development of the Observer Model.

  5. 24. Direct Digital Frequency Synthesis in Field-Programmable Gate Arrays

    University essay from Institutionen för systemteknik

    Author : Petter Källström; [2010]
    Keywords : PSAC; DDFS; FPGA; Matlab; Frequency Synthesis;

    Abstract : This thesis is about creation of a Matlab program that suggests and automatically generates a Phase to Sine Amplitude Converter (PSAC) in the hardware language VHDL, suitable for Direct Digital Frequency Synthesis (DDFS). Main hardware target is Field Programmable Gate Arrays (FPGAs). READ MORE

  6. 25. 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.
