Għaliex it-trasmettituri tal-vidjo mingħajr fili fuq distanza twila jirrakkomandaw vantaġġ cofdm

COFDM, Multiplexing tad-Diviżjoni tal-Frekwenza Ortogonali Kodifikata
1. Requires much narrower bandwidth than analog’s
2. Resistant to multi-path
3. Robust signal in NLOS (mhux linja tal-vista)–Performing inside buildings, through walls, and around corners
4. Error correction & strong encryption
5. High performances on aircraft, vehicles, vapuri
6. Performs well in high-speed moving transmission
