Kaupapa:He tino ngawari te maapono o te punaha Tirohanga Whakawhitinga Tika.Hei tauira, ka whakawhänuihia he aho o ngä pärongo ka tukuna ki tëtahi roopu auau tino whanui na roto i te waehere PN.I te mutunga o te whiwhinga, ka tikina nga korero ka tukuna ma te hono i te tohu awhiowhio hora me te waehere PN kotahi i whakamahia mo te roha i te mutunga tuku.
Te kaupapa hohonu:Tuatahi, ka whakamahi tika ia i te raupapa waehere hihinga horahanga me te reeti waehere teitei ki te hora i te hihinga o te tohu i te kaikawe ma te whakamahi i nga momo tikanga whakarereke, katahi ka whakamahia e ia te raupapa o te raupapa tohu whaanui horapa ki te wetewete i te kaiwhiwhi ki te whakahoki i te horapa. tohu tūāwhiorangi ki ngā kōrero taketake.Me pehea te hora i te awhiowhiotanga: Inaa, ka whakamahia he tikanga whakarereke mamati.Inaa, ka whakamahia he waehere PN (waehere haruru) hei taapiri i te puna tohu.Hei tauira, ina hiahia te kaiwhakawhiti ki te tuku tohu, whakakapihia te "1" ki te 110001000110 me te "0" ki te 00110010110. Ko tenei tukanga ka mohio ki te whanui whanui.I te kaiwhiwhi, mena ko te raupapatanga kua riro ko 110001001110, ka whakahokia ki te “1″ me te mea ko “00110010110,” ka whakahokia ki te “0″.Ka kiia tenei ko “te taro.I tenei ara, ka piki ake te reeti puna tohu e 11 nga wa, a ko te whiwhinga tukatuka he nui atu i te 10dB, e pai ake ana te pai o te owehenga haruru maha o te miihini katoa.
Ko te whanui RF o te punaha DSSS he tino whanui.Na reira, ko tetahi waahanga iti o te awhiowhio e kore e tino memenge o te awhi tohu, koinei tetahi o ona painga.He tino pai te DSSS mo tona haumarutanga, na reira i whakamahia e te ope hoia o Amerika mo te tuku ahokore i te Pakanga Tuarua o te Ao.
Ko runga ake nei ko te whakamaramatanga matauranga mo te Whakawhitinga Whakawhitinga Turanga (DSSS) - Maapono Whakawhitiwhiti i kawea mai ki a koe eShenzhen HDV Optoelectronic Technology Co., Ltd., he kaihanga o nga taputapu korero whatu.Ko te tumanako ka awhina tenei tuhinga ki a koe ki te whakanui ake i to matauranga.Mauruuru koe mo te panui i tenei tuhinga.
