Title: | Communication system performance: Achieving the ultimate information-theoretic limits? | Authors: | Drajic D. Bajić, Dragana |
Issue Date: | 1-Jun-2002 | Journal: | IEEE Communications Magazine | Abstract: | In this article, the role of information theory in communications is considered, the former giving the ultimate limits and sometimes showing how to approach them. A short survey of the development of telephone channel modems, where the capacity is practically achieved, is presented. As a contrast, a very short account of multi-antenna systems is included, where a long journey to achieve capacity has just begun. A very important characteristics of multi-antenna systems is stressed: the capacity increases almost linearly with respect to transmitted power as the number of antennas increases, keeping the corresponding bandwidth constant. | URI: | https://open.uns.ac.rs/handle/123456789/12764 | ISSN: | 1636804 | DOI: | 10.1109/MCOM.2002.1007418 |
