Description
  • Tématem tohoto příspěvku je obnova nosného kmitočtu. Pozornost byla soustředěna na implemetaci a simulaci dvou optimalizačních metod v Matlabu. Porovnávány byly metoda nejstmějšího sestupu a Newtonova metoda. Simulovaný systém obsahoval generátor gererující datový signál o N úrovních, který byl dále modulován, umocněn a pásmově filtrován. Tímto procesem vznikl signál vhodný pro simulaci. Výstupem simulací byly časové závislosti odhadu fázového kmitočtu a průběh obnoveného datového signálu. (cs)
  • This paper is focused on a carrier frequency recovery. Two optimization methods utilized for the indirect frequency estimation were chosen to be implemented and simulated in Matlab. The steepest descent method and Newton’s method are described in detail and compared. The simulation pre-processor includes a generator of N-level binary message signal which is modulated, squared and band-pass filtered to obtain a proper form of received signal which is processed in simulation engine. The time dependences of phase offset estimates and recovered message signal are the results of simulation.
