Kwa nini visambazaji video vya masafa marefu visivyotumia waya vinapendekeza faida ya cofdm?
COFDM, Msimbo Orthogonal Frequency Division Multiplexing
1. Requires much narrower bandwidth than analog’s
2. Resistant to multi-path
3. Robust signal in NLOS (zisizo mstari wa mbele)–Performing inside buildings, through walls, and around corners
4. Error correction & strong encryption
5. High performances on aircraft, vehicles, ships
6. Performs well in high-speed moving transmission
