Ihame:Ihame rya Directeur ikurikiranye Ikwirakwizwa rya Spectrum sisitemu iroroshye cyane. Kurugero, umurongo wamakuru woherejwe waguwe kumurongo mugari cyane ukoresheje kode ya PN. Ku iherezo ryakiriwe, amakuru yoherejwe agarurwa muguhuza ibimenyetso byo gukwirakwiza ibimenyetso hamwe na kode imwe ya PN ikoreshwa mu kwaguka kurangiza.
Ihame ryimbitse:Ubwa mbere, ikoresha mu buryo butaziguye ikwirakwizwa rya kode ikurikirana hamwe n’igipimo kinini cyo hejuru kugira ngo ikwirakwize ibimenyetso byerekana ibimenyetso kuri transmitter ikoresheje uburyo butandukanye bwo guhindura ibintu, hanyuma ikoresha uburyo bumwe bwo gukwirakwiza kodegisi ikurikirana kugira ngo isubize ibyakiriwe kugira ngo isubize ikwirakwizwa. Ikimenyetso cyerekana amakuru yumwimerere. Uburyo bwo gukwirakwiza ibintu byihariye: Mubyukuri, uburyo bwa modulasiyo ikoreshwa. By'umwihariko, code imwe ya PN (code ya pseudo-urusaku) ikoreshwa mukongeramo ibimenyetso. Kurugero, mugihe transmitter ikeneye kohereza ibimenyetso, simbuza “1 ″ na 110001000110 na“ 0 ″ na 00110010110. Iyi nzira imenya ibintu byinshi. Kubakira, niba urutonde rwakiriwe ari 110001001110, ruzasubizwa kuri “1 ″ kandi niba ari“ 00110010110, ”ruzasubizwa kuri“ 0 ″. Ibi byitwa "umutsima. Muri ubu buryo, igipimo cyerekana ibimenyetso byiyongereyeho inshuro 11, kandi inyungu yo gutunganya irenze 10dB, iteza imbere neza urusaku rwinshi rw urusaku rwimashini yose.
Umuyoboro wa RF wa sisitemu ya DSSS ni mugari cyane. Kubwibyo, agace gato ka specran ntikuzatera kugabanuka gukabije kwikimenyetso, nikimwe mubyiza byacyo. DSSS ni indashyikirwa mu mutekano wayo, niyo mpamvu ingabo z’Amerika zayikoresheje cyane mu gukwirakwiza insinga mu Ntambara ya Kabiri y'Isi Yose.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwibisobanuro bikwirakwizwa bikwirakwizwa (DSSS) Itumanaho - Ihame ryitumanaho ryazanwe naShenzhen HDV Optoelectronic Technology Co., Ltd.., uwakoze ibikoresho byitumanaho rya optique. twizere ko iyi ngingo ishobora kugufasha kongera ubumenyi.
