Przedstawiono zasadę działania kanału transmisyjnego z zastosowaniem wynalezionych w roku 1993 turbokodów. Kody te pozwalają zbliżyć się do granicy teoretycznej przepustowości kanału przy transmisji w obecności szumu, wyznaczonej przez CIauda Shannona w roku 1948. Praca jest adresowana do szerokiego kręgu osób zainteresowanych, niekoniecznie specjalistów w dziedzinie kodowania. Dla specjalistów zamieszczono obszerną bibliografię. Opisano również w zwięzły sposób niektóre zastosowania turbokodów.

The principles of digital transmission in the presence of noise using the recently invented (1993) turbo codes arę presented. The turbo codes have a performance in terms of bit error probability very close to the Shannon limit. In principle the paper is addressed to a large forum of nonspecialist in the coding theory. However a large bibliography Is addressed to specialists. A brief description of present and future applications is included.
