dc.description.abstractENGLISH ABSTRACT: The purpose of this thesis is the description of the development of a QPSK demodulator for the Sunsat 1 groundstation. A general overview of the functioning and requirements of a typical QPSK demodulator system is given. Several methods or algorithms for clock and carrier recovery are discussed. Specific attention is given to the QPSK demodulator chipset from Philips used for the implementation of the demodulator. The digital decoding logic used to serialize the parallel I and Q datastream is explained. Finally measurement techniques for performance evaluation of QPSK systems are investigated. As part of this the implementation loss of the developed QPSK demodulator is measured.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die doelwit van hierdie tesis is om die ontwikkeling van 'n QPSK demodulator vir die Sunsat 1 grondstasie te beskryf. 'n Algemene oorsig oor die funksionering en vereistes van 'n tipiese QPSK demodulator stelsel word gegee. Verskeie algoritmes en tegnieke vir klok en draersein herwinning word ondersoek en bespreek. Spesifieke verwysing word telkens gemaak na die QPSK demodulasie vlokkie paar van Philips gebruik vir die implementering van die demodulator. Die digitale dekodering logika benodig vir die datastroom verpakking word ondersoek en beskryf. Laastens word daar gekyk na meettegnieke en evaluasie van QPSK demodulasie stelsels se prestasie. As deel hiervan word die implementasie verlies van die ontwikkelde QPSK demodulator stelsel gemeet.af_ZA
