Simulation Ib puag ncig: DVB-T / T2 Modulator, Ntawm Plains, thiab tsis muaj cov khoom baffle nyob ib puag ncig. Qhov siab ntawm tus pej thuam: D*D=17H(D: Transmission Radius; H: Ntauwd Qhov siab). Qhov kev sib kis tiag tiag yuav ntau dua lossis tsawg dua, nyob ntawm qhov ua tau zoo.

PS: Cov ntaub ntawv tsuas yog siv rau kev siv, pab cov neeg siv khoom los ua qhov kev pabcuam thawj zaug; Qhov kev ncua deb tiag tiag yog qhov txawv ntawm tus nqi theoretical.
Hom kev pom zoo thiab tus nqi sib thooj me ntsis
16 QAM DVB-T (21MB) DVB-T2 (27MB)
64QAM DVB-T (27MB) DVB-T2 (35MB)"
Cov qauv yog ib qho kev xam qhov deb ntawm ib zaug, xws li ntau zaus point (broadband transmitter)
Piv txwv 1:
Yog tias tus neeg siv khoom xav tau kev xa tawm 29KM, siv 16QAM kev hloov pauv, thiab sib xyaw 5 lub tshuab xa hluav taws xob nrog 5 zaus cov ntsiab lus, tom qab ntawd ib qho chaw zaus 29KM xav tau 350W transmitter, ces 5 zaus cov ntsiab lus xav tau 350x5=1750W wideband transmitter.
Piv txwv 2:
Yog tias tus neeg siv khoom xav tau xa tawm 15KM, siv 64QAM kev hloov pauv, thiab sib xyaw 6 lub tshuab xa hluav taws xob nrog ib qho zaus, tom qab ntawd ib qho chaw zaus 15KM xav tau 180W transmitter, ces 6 zaus zaus xav tau 180x6=1080W wideband transmitter.
