Perché i trasmettitori video wireless a lunga distanza consigliano il vantaggio cofdm

COFDM, Multiplexing a divisione di frequenza ortogonale codificata
1. Requires much narrower bandwidth than analog’s
2. Resistant to multi-path
3. Robust signal in NLOS (non linea di vista)–Performing inside buildings, through walls, and around corners
4. Error correction & strong encryption
5. High performances on aircraft, veicoli, navi
6. Performs well in high-speed moving transmission
