Why do long-distance wireless video transmitters recommend cofdm advantage?

COFDM, Coded Orthogonal Frequency Division Multiplexing 1. Requires much narrower bandwidth than analog's 2. Resistant to multi-path 3. Robust signal in NLOS (non-line of sight)--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

Pemancar video nirkabel jarak jauh COFDM merekomendasikan 2022

Mengapa pemancar video nirkabel jarak jauh merekomendasikan keuntungan cofdm??

COFDM, Multiplexing Divisi Frekuensi Ortogonal Berkode
1. Membutuhkan bandwidth yang jauh lebih sempit daripada analog
2. Tahan terhadap multi-jalur
3. Sinyal kuat di NLOS (non-line of sight)–Pertunjukan di dalam gedung, menembus dinding, dan di sekitar sudut
4. Koreksi kesalahan & enkripsi yang kuat
5. Performa tinggi di pesawat, kendaraan, kapal
6. Berkinerja baik dalam transmisi bergerak berkecepatan tinggi
