No ni'a i te video i ni'a nei:
Ta tatou mau tao'a matau - roa ' ' e - hia, o te mau tao'a video ïa aita e niuniu paraparau e te mau afata afata teata. Tera ra, e titau te tahi mau hoani i te tauiraa i te taime haponoraa no te pahono i te mau aniraa i te pae o te ture o te fenua iho, i reira te ofa'i jade e tae mai ai i ni'a i te matini roro uira. Ua ani mai te hoê hoani e ia faaohipa matou i te RF frequency i raro a'e i te hoho'a video no ta'na 2.4G. No reira, e 2.4GHz, e 600MHz, and the lowdown frequency is 1800MHz. Ua hamani matou i te hoho'a ia au i ta'na mau parau taa ê. So I showed him a simple video that showed the 2.4G transmitter and 600Mhz receiver working correctly. Mai te peu e hoê â titauraa ta outou, mai te 1-3G frequency input and 300-700Mhz output, a farerei mai na ia matou no te hoê rave'a i matarohia.
TE MAU NOTA
Te hoê ofa'i hi'opo'a (BDC) no te mau haapurororaa video aita e niuniu uira, o te hoê ïa matini o te nehenehe e taui i te hoê anairaa o te pinepineraa o te tere i nia i te hoê faito raro roa.
E faaohipa - pinepine - hia i te pae o te mau ripene video aita e niuniu paraparau. Ei hioraa,
- Mai te 5.8G e tae atu i te 2.400
- Mai te 2.4G e tae atu i te 1.20
- Mai te 1.2G e tae atu i te 600Mhz
Te tumu, no te mea ïa e ua taotiahia te mau haapurororaa niuniu ore i roto e rave rahi mau fenua aore ra mau tuhaa fenua e te mau ture e te mau faatureraa o te fenua.
Eita te reira e faatiahia ia faaohipa i roto i te hoê anairaa taa ê.
No te taui i te pinepineraa o te tereraa o te matini e te afata apo parau, down-conversion or up-conversion is required. A haapapu e te tuea ra te pinepineraa o te faataeraa ia au i te mau ture e te mau faatureraa o te fenua.
Te vai atoa ra te hi'oraa i reira te taata aravihi e farii ai i te parau faati'a, ei hioraa, i rotopu i te 300-800Mhz.
In order for the transmitter's frequency to be paired, te mea ti'a ia faaitihia te rahiraa o te mau 1.20.
E titau teie mau mea atoa i te faaohiparaa i te hoê ravea haapurororaa video aita e niuniu paraparau..
E, ua pahono mai to matou taata aravihi, e nehenehe ta tatou e rave i te reira. E, na mua a'e i te fanauraa, e faaite atu matou ia outou i te hoho'a video hi'opo'a.
E, te haapapû nei to tatou taata aravihi e, e nehenehe ta tatou e hamani faahou e e taui i te tahi mau tuhaa faufaa no te rave i te reira. E mea papû, na mua a'e i te fanauraa, e faaite atu matou ia outou i te hoho'a video hi'opo'a.

Te vai noa ra te hoê uiraa?
A farerei mai na ia matou no te tahi atu mau haamaramaramaraa.
A hapono i ta outou uiraaE aha te DDC
I roto i te hamaniraa papai signal roro uira, te mau raro-converter (DDC) i te feia faafariu e digitized, Te tapa'o faaite no te hoê tapa'o i ni'a i te hoê faito raro a'e, no te faaohie ïa i te mau tuhaa o te ratio i muri mai. Faanahoraa no te faaherehere i te mau haamaramaramaraa atoa i roto i te te tapao iti o te moe i te rounding i te mau hape i roto i te ravea no te mathematical. E nehenehe e e te input e te output i te tapao i te hohoa o te parau mau e aore ra te fifi. E mea pinepine te DDC i te feia faafariu mai roto mai i te ota ratio pinepine e aore ra, i te hoe taime ropu tae roa i te hoe tapao no te baseband te fifi.
To
Te DDC i roto e toru subcomponents: te synthesizer e i te mau (DDS), hoe titia low te tere (LPF), and a down sampler (e integrated i te o i roto i te titia low te tere). Te faatupu nei te DDS i te hoê fifi rahi i te taime a tupu ai te reira i rotopu i te mau taata. (MAI TE MEA E). Multiplication i te taime taa e te faaararaa i te input e faatupu i te mau hohoa ia faatumuhia i nia i te taatoaraa e te taa e i te taime (o te tupu mai i muri a'e i te ati rahi i tupu i ni'a i te pahi ra Fourier). The low-pass filters pass the difference (i.e. baseband) pinepine a te patoiraa i te taatoaraa ia pinepine te hohoa, te hoho'a o te tapa'o matamua. Te rave-faaoti-raa i te hoê ma'itiraa no ni'a i te ti'amâraa e te LPF, e tu'ati te tapa'o taa ê i te tapa'o matamua. I roto i to ' na huru apî, it can readily be down-sampled and is more convenient to many DSP algorithms. E nehenehe e faaohipa i te mau titi'a e tano no te tuu i roto i te FIR, TE MAU NOTA, e te mau titi'a. Te ma'itiraa matau-roa-hia a'e, o te hoê ïa titi'a no te mau faito raro roa (iti mai i te ahuru) or a CIC filter followed by an FIR filter for larger down-sampling ratios.
Te mau tauiraa i nia i te DDC
E rave rahi mau taa - ê - raa i nia i te DDC o te tauturu ia tatou, e tae noa'tu i te mau taata e rave rahi o te tuu i te hoê tapa'o faaite i roto i te DDS. Oia ho'i te:
- Decision-directed carrier recovery phase-locked loops in which the I and Q are compared to the nearest ideal constellation point of a PSK signal, e ua titi'ahia e ua faaho'ihia te tapa'o no te hape i roto i te DDS
- Te hoê e'a turu i reira te I e te Q e faarahihia'i e e hi'opo'ahia'i ei tuhaa no te hoê BPSK/QPSK carrier
Faaohiparaa
E mea pinepine te mau DDCs i te faaohipahia i roto i te feruriraa i roto i te mau faanahoraa e nehenehe e faaohipahia e aore râ, i roto i te mau faanahoraa no te faaohiparaa. E nehenehe atoa te mau faaohiparaa i te faanahoraa roro uira e faaohipahia, Te mau ohipa i ravehia i roto i te DDS, Te mau mana'o tauturu no te, and input stages of the low-pass filters all run at the sampling rate of the input data. E rave-ti'a-hia teie mau haamaramaramaraa mai te faaauraa e tae atu i te mau taata faafariu-apî-hia (Te mau mana'o tauturu no te haapiiraa) E mau ahuru e aore râ, e rave rahi hanere MHz. CORDIC is an alternative to the use of multipliers in the implementation of digital down converters.
