Musimboti:Nheyo yeiyo Direct Sequence Spread Spectrum system iri nyore. Semuenzaniso, tambo yeruzivo rwekutumirwa inowedzerwa kune yakakura kwazvo frequency bhendi kuburikidza nePN kodhi. Pakupera kwekugamuchira, ruzivo rwakatumirwa runotorwa nekubatanidza chiratidzo chekupararira neiyo PN kodhi imwechete inoshandiswa pakuwedzera pakupera kwekutumira.
Nheyo yakadzama:Chekutanga, inoshandisa zvakananga kupararira spectrum kodhi yakatevedzana ine yakakwira kodhi chiyero kuparadzira iyo spectrum yechiratidzo pane transmitter nekushandisa dzakasiyana siyana modulation nzira, uyezve inoshandisa iyo yakafanana kupararira spectrum kodhi kutevedzana kudhirodha pane anogamuchira kudzoreredza kupararira. spectrum chiratidzo kune yepakutanga ruzivo. Maitiro ekuparadzira spectrum zvakananga: Muchokwadi, nzira yedhijitari modulation inoshandiswa. Kunyanya, imwe PN kodhi (pseudo-noise kodhi) inoshandiswa kuwedzera chiratidzo chechiratidzo. Semuyenzaniso, kana chinofambisa chichida kutumira masaini, chinja “1″ ne110001000110 uye “0” ne00110010110. Iyi nzira inoona yakakura. Pamugamuchiri, kana kutevedzana kwakagamuchirwa kuri 110001001110, inodzoserwa ku “1″ uye kana iri “00110010110,” inodzoserwa ku “0”. Izvi zvinonzi “chingwa. Nenzira iyi, chiyero chechiratidzo chechiratidzo chinowedzerwa nekagumi neimwe, uye kuwana kwekugadzirisa kunopfuura 10dB, iyo inovandudza zvinobudirira huwandu hweruzha rwemuchina wese.
Iyo RF bandwidth yeDSSS system yakakura kwazvo. Naizvozvo, chikamu chidiki cheiyo spectrum hachizokonzeri kupera kwakakomba kwechiratidzo chechiratidzo, chinova chimwe chezvakanakira. DSSS yakanaka kwazvo mukuchengetedzeka kwayo, ndosaka mauto eUS ainyanya kuishandisa kutapurirana zvisina waya panguva yeHondo Yenyika II.
Zviri pamusoro ndiyo tsananguro yeruzivo yeDirect Sequence Spread Spectrum (DSSS) Kukurukurirana - Nheyo yeKukurukurirana yakaunzwa kwauri ne.Shenzhen HDV Optoelectronic Technology Co., Ltd., mugadziri we optical communication equipment. Ndinovimba chinyorwa ichi chinogona kukubatsira iwe kuwedzera ruzivo rwako. Ndinotenda nekuverenga chinyorwa ichi.
