Abstract
U radu je dana analiza spektra i vjerojatnosti pogreške QAM signala. QAM modulacijski postupci osiguravaju veću udaljenost signala u prostoru signala u odnosu na MPSK signale rezultirajući manjom vjerojatnosti pogreške te većom otpornosti na šum. Rezultatom simulacije u programskom paketu Matlab prikazan je odnos vjerojatnosti pogreške ! i omjera energije signala i snage šuma, S/" za 16QAM, 64QAM i 256QAM. 16QAM ima najmanju vjerojatnost pogreške od tri promatrana modulacijska postupka, dok 256QAM prenosi najviše podataka u jedinici vremena

Parallel abstract (English)
In this work it si given spectrum and error probability analyse of QAM signals. QAM modulation provides greater distance between signals in signal space considering MPSK signals resulting with greater noise resistance. With simulation in Matlab it is shown relationship between error probability ! and signal/noise power S/" for 16QAM, 64QAM and 256QAM. 16QAM has lowest error rate considering three observed process while 256QAM can transmit the most information in time
