OFDM (anglicky Orthogonal Frequency Division Multiplexing, ortogonální multiplex s frekvenčním dělením) je širokopásmová modulace využívající frekvenční dělení kanálu. Pracuje s tzv. rozprostřeným spektrem, kdy je signál vysílán na více vzájemně ortogonálních frekvencích , které jsou označovány jako subnosné.
The analysis highlights Overview, Related Topics and Entities as prominent areas in the source structure around OFDM.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
