    Kukurukurirana System Model

    Nguva yekutumira: Nov-21-2024

    1. Inokamurwa nebasa rekutaurirana

    Zvinoenderana nemhando dzakasiyana dzemasevhisi ekufambiswa kwemashoko, masisitimu ekutaurirana anogona kukamurwa kuita masisitimu enharembozha, masisitimu ekufambisa mashoko enhare, masisitimu ekufambisa mashoko, masisitimu ekufambisa mifananidzo, nezvimwewo. Nekuti network yenharembozha ndiyo inonyanya kugadzirwa uye ine mukurumbira, mamwe masevhisi ekufambisa kazhinji inofambiswa kuburikidza nenharembozha yeruzhinji network, senge telegraph kutaurirana uye kureba kwedata data inogona kufambiswa kuburikidza nechiteshi chenhare. Yakabatanidzwa sevhisi yedhijitari yekutaurirana network inokodzera kuendesa ruzivo rwemhando dzakasiyana dzesevhisi.

    2. Yakarongedzwa ne modulation mode

    Zvinoenderana nekuti chiratidzo chinofambiswa muchiteshi chakagadziridzwa here kana kuti kwete, iyo yekutaurirana system inogona kukamurwa kuita baseband transmission system uye bandpass transmission system. Baseband kutapurirana ndiko kutapurirana kwakananga kwemasaini asina kurongeka, akadai senhare yemuno, tambo yekutepfenyura; Bandpass kutapurirana ishoko rakajairika rekuchinjisa kufambisa kwemasaini akasiyana. Kune dzakawanda nzira dzemodulation, uye Tafura 1-1 inonyora dzimwe dzakajairika modulation nzira.

    3. Kuronga maererano nezviratidzo zvezviratidzo

    Zvinoenderana nechiteshi chekufambisa chiratidzo cheanalog kana chiratidzo chedhijitari, sisitimu yekutaurirana yakakamurwa kuita analog yekutaurirana system uye dijitari yekutaurirana system.

    4, zvinoenderana neiyo transmission medium classification

    Zvinoenderana neyekutapurirana svikiro, iyo yekutaurirana system inogona kukamurwa kuita waya yekutaurirana system uye isina waya yekutaurirana system. Kukurukurirana kwewaya ndiko kushandiswa kwewaya (yakadai sewaya yakavhurika pamusoro, coaxial tambo, optical fiber, waveguide, nezvimwewo) senzira yekutapurirana kuti ipedze kutaurirana, senge runhare rweguta, tambo TV, submarine cable kutaurirana. Kukurukurirana kusina waya kunovimba nemagetsi ekuparadzira mafungu munzvimbo kuti azadzise chinangwa chekufambisa ruzivo, senge pfupi-wave ionospheric kuparadzira, microwave mutsara-we-kuona kuparadzira, satellite relay uye zvichingodaro.

    5, maererano nekushanda bhendi classification

    Zvinoenderana nekushanda frequency kana wavelength yemidziyo yekutaurirana, yakakamurwa kuita kutaurirana kwenguva refu, kutaurirana kwemafungu epakati, kutaurirana kwenguva pfupi, kutaurirana kure infrared zvichingodaro.

    6, zvinoenderana nechiratidzo chekuwedzera kupatsanura

    Kune matatu ekutanga ekuwedzera mamodhi ekufambisa masaini akawanda, anoti frequency division multiplexing, nguva yekuparadzanisa kuwanda uye kodhi division multiplexing. Frequency division multiplexing ndeyekuita kuti masaini akasiyana atore akasiyana ma frequency renji nenzira yekuchinja kwe spectrum. Nguva yekuparadzanisa kuwanda kunoshandisa pulse modulation kuita kuti masaini akasiyana atore nguva dzakasiyana. Code division multiplexing ndiko kushandiswa kweorthogonal encoding kutakura masaini akasiyana. Frequency division multiplexing inoshandiswa mune yechinyakare analog kutaurirana. Nekuvandudzwa kwekutaurirana kwedhijitari, nguva yekuparadzanisa kuwanda kunoshandiswa zvakanyanya uye zvakanyanya. Code division multiplexing inoshandiswa munzvimbo yekutaurirana kuparadzira spectrum kutaurirana uye nhare yekutaurirana system. Mukuwedzera, kune wavelength division multiplexing, nzvimbo yekuparadzanisa multiplexing.
