Abstract
Konvolucijsko kodiranje zaštitno je kodiranje podataka u prijenosu. Takva vrsta kodiranja potrebna je kako bi se informacija zaštitila, da i nakon dekodiranja ne gubi svoj smisao. Konvolucijsko kodiranje, za razliku od blok kodova, uzima struju informacija i kodira ju. Prema tome kodna riječ može biti beskonačne duljine, a razlog je tome što i ulazna poruka isto tako može biti neograničena. Konvolucijsko kodiranje objasnit će se na primjerima dijagram stanja, dijagrama stabla, dijagrama rešetke, kodiranjem s memorijskim elementima. Nadalje, u radu će se govoriti o postupcima dekodiranja konvolucijskim kodovima kako bi potpuno razumjeli način konvolucijskog utjecaja na informaciju. Objasnit će se dva postupka dekodiranja, serijsko dekodiranje i Viterbijevo dekodiranje. Kroz analizu četiri vrste kodera pokazat će se da postoje razlike bez obzira što se koriste koderi s istom kodnom brzinom. Pokazat će se da koderi s različitim brojem memorijskih elemenata imaju drukčije vrijeme kodiranja, a rade s istom duljinom ulaznog niza bitova. Dokazat će se da simulacija i ručno kodiranje putem generatorskog polinoma daju isti kodirani niz. Grafički će se prikazati rezultati analize te njihova usporedbu.
Abstract (english)
Convolutional code is a protected encoding of data in transmission. This type of coding is needed for data protection so that it does not lose its meaning even after the decoding process. Unlike block codes, convolutional coding takes a stream of data and encodes it. That code can be of infinite length because the input message can also be of infinite length. Convolutional coding will be shown using the examples of tree diagrams, lattice diagrams and with coding using memory elements. Furthermore, the ways of decoding using convolutional codes will be discussed, to fully understand the way convolution affects information. Two ways of decoding, serial decoding, and Viterbi decoding will be explained. It will be shown whether there are any differences between four types of encoders with the same encoding rate. The encoders with different number of memory elements have different encoding times while encoding the same length of the input bit string. It will be proven that simulation and manual coding with a polynomial generator gives the same coded sequence. The results will be compared and graphically represented
