Abstract
Polazeći od analize prirode, metoda redukcije, sažimanja, kodiranja i prijenosa audio signala te multimedijalnih i ostalih podataka u GSM sustavu moguće je ustanoviti mjesta u prijenosnom lancu na kojima dolazi do degradacija kvalitete, kao i mehanizme GSM sustava korištenjem kojih se degradacije u prijenosu mogu smanjiti. Cilj je ovog rada uvesti odgovarajuće subjektivne i objektivne mjerne postupke za ocjenu kvalitete prijenosa te na osnovi provedenih mjerenja u realnim uvjetima predložiti načine otkrivanja degradacija i metode optimizacije prijenosa signala koristeći se raspoloživim GSM upravljačkim mehanizmima. Razvijen je informacijski sustav za obradu i analizu mjerenja radijskog sučelja te automatski programski moduli za optimizaciju mreže. Razvijeni algoritmi i metode poboljšanja prijenosa testirani su i primijenjeni u komercijalnoj uporabi.
Abstract (english)
By analyzing the nature, reduction and compression methods, coding and transmission of audio signal, rich contents (multimedia) and other data in GSM system, it is possible to determine points in the transmission chain where different degradations of quality occur as well as the GSM mechanisms using which the effect of such degradations can be reduced. The objective of this thesis is to introduce relevant subjective and objective measurment methods for evaluation of transmission quality and, based on measurements in real-life conditions, propose methods for detecting degradations and optimizing signal transmission using available GSM control mechanisms. An information system for processing and analyzing radio subsystem performance measurement was developed as well as automatic software modules for optimizing the network. Developed algorithms and methods for improving the transmission have been tested and used in commercial network operation.
