1. Qhov twg yog nyob ntawm orthogonality? Nqe lus piav qhia: FDM txheej txheem yog ua raws li qhov orthogonality ntawm sinusoids.
Yuav ua li cas los ntawm orthogonality?
Frequency Division Multiplexing (FDM) yog nyob ntawm orthogonality. Kev piav qhia: Zaus Division Multiplexing (FDM) yog cov txheej txheem sib txuas uas muaj ntau cov ntaub ntawv qhia tau ua ke rau kev sib kis ib txhij ntawm kev sib txuas lus nruab nrab.
Dab tsi yog qhov tsis yog orthogonal multiplexing?
Non-orthogonal zaus-division multiplexing (N-OFDM) yog txheej txheem ntawm kev encoding digital cov ntaub ntawv ntawm ntau tus neeg nqa khoom zaus nrog tsis yog-orthogonal ntu nruab nrab ntawm zaus ntawm sub-carriers. N-OFDM cov teeb liab tuaj yeem siv rau hauv kev sib txuas lus thiab radar systems.
Yuav ua li cas siv Mcq?
Kev piav qhia: Kev sib xyaw yog siv txhawm rau tiv thaiv tag nrho cov teeb liab me me hauv PCM los ntawm quantizing nrov.
Qhov system twg siv QAM Mcq?
Kev piav qhia: Digital microwave relay, hu xov tooj rau modem thiab lwm yam siv QAM cov txheej txheem hloov kho.
