Abstract

U ovom radu analizirana je mogućnost implementacije statističkog multipleksiranja u sustavu za prijem televizijskog signala na dlanovnicima (DVB-H). Na praktičnim primjerima analizirana je potrošnja energije te spektralna učinkovitost determinističkog i statističkog multipleksiranja. Provedena je usporedba energetske i spektralne učinkovitosti ove dvije vrste multipleksiranja u uvjetima mobilnog prijema. Rezultati pokazuju da je primjenom statističkog multipleksiranja moguće poboljšati spektralnu učinkovitost za 30% do 45% uz neznatno povećanje potrošnje energije za 2% do 5% u odnosu na determinističko multipleksiranje.

Abstract (english)

This research analyzed the possibility of implementing statistical multiplexing in DVB-H system. Energy consumption and spectral efficiency of deterministic and statistical multiplexing was analyzed on practical examples. Comparison of energy and spectral efficiency was made for these two types of multiplexing in terms of mobile reception. The results show that with use of statistical multiplexing it is possible to improve spectral efficiency by 30% to 45% with only a slight increase in power consumption (2% - 5%) compared to deterministic multiplexing.
