Ngwakọta

Na sistemụ nkwukọrịta ekwentị ikuku, ọrụ bụ isi nke ihe na-agwakọta bụ ijikọta akara ntinye ọtụtụ band wee wepụta ha na otu sistemụ nkesa dị n'ime ụlọ.

N'ọrụ injinia, a ga-ewepụta netwọk 800MHz C, netwọk 900MHz G ma ọ bụ ugboro ole dị iche iche n'otu oge. Site na iji ngwakọta, otu sistemụ nkesa dị n'ime ụlọ nwere ike ịrụ ọrụ na band CDMA, band ugboro ole GSM ma ọ bụ band ugboro ole ndị ọzọ n'otu oge.

Dịka ọmụmaatụ, na sistemụ antenna redio, a na-ejikọta akara ntinye na mmepụta nke ọtụtụ eriri ugboro dị iche iche (dịka 145mhz na 435mhz) site na igwekota, wee jikọọ ya na ọdụ redio na ihe na-enye nri, nke na-azọpụtaghị naanị ihe na-enye nri, kamakwa ọ na-ezere nsogbu nke ịgbanwe antenna dị iche iche.

 

 

Emmetụta

N'ọrụ injinia, ọ dị mkpa ijikọta netwọk 800MHz C na netwọk 900MHz G. Site na iji ihe njikọta, otu sistemụ nkesa ime ụlọ nwere ike ịrụ ọrụ na band CDMA na band GSM n'otu oge. Maka ihe atụ ọzọ, na sistemụ antenna redio, a na-ejikọta akara ntinye na mmepụta nke ọtụtụ band ugboro dị iche iche (dịka 145mhz na 435mhz) site na ihe njikọta, wee jikọọ ya na ọdụ redio na ihe ntinye, nke na-azọpụta naanị ihe ntinye, kamakwa na-ezere nsogbu nke ịgbanwe antenna dị iche iche..

 

Nkọwa ihe atụ nke ụkpụrụ

A na-ejikarị ihe njikọta eme ihe n'akụkụ mgbasa ozi. Ọrụ ya bụ ijikọta akara RF abụọ ma ọ bụ karịa sitere na ihe nnyefe dị iche iche wee ziga ha na ngwaọrụ RF nke antenna na-ebuga, ebe a na-ezere mmekọrịta dị n'etiti akara nke ọdụ ụgbọ mmiri ọ bụla.

Ngwakọta na-enwekarị ọdụ ụgbọ mmiri ntinye abụọ ma ọ bụ karịa na naanị otu ọdụ ụgbọ mmiri mmepụta. Mwepụ ọdụ ụgbọ mmiri bụ ihe dị mkpa iji kọwaa ikike nke akara abụọ na-anaghị emetụta ibe ha. A na-achọkarị ka ọ karịrị 20dB.

Ngwakọta akwa mmiri 3dB nwere ọdụ ụgbọ mmiri ntinye abụọ na ọdụ ụgbọ mmiri mmepụta abụọ, dịka egosiri na Foto nke 2. A na-ejikarị ya emepụta ugboro abụọ nke ikuku na-ebufe ma na-etinye ha n'ime antenna ma ọ bụ sistemụ nkesa. Ọ bụrụ na ejiri naanị otu ọdụ ụgbọ mmiri mmepụta, ọ dị mkpa ka ejikọta ọdụ ụgbọ mmiri mmepụta nke ọzọ na ibu 50W. N'oge a, enwere mfu 3dB mgbe ejikọtara mgbaàmà ahụ. Mgbe ụfọdụ, ọ dị mkpa ka ejiri ọdụ ụgbọ mmiri mmepụta abụọ ahụ, yabụ na enweghị ibu na mfu 3dB.

Jikọta nnata na izipu ekwentị mkpanaaka na otu antenna. N'ime sistemụ GSM, ebe ọ bụ na antenna ahụ anọghị n'otu oge, ekwentị mkpanaaka nwere ike ịhapụ duplexer ahụ maka ikewapụ antenna ahụ, ma jiri naanị antenna dị mfe jikọta antenna izipu na ịnata ya n'otu antenna na-enweghị nsogbu n'etiti onwe ha.

Maka sekit nnata, antenna ahụ na-anata mgbaàmà ahụ, na-abanye na ọwa nnata site na igwekota, na-agwakọta ya na mgbaàmà oscillator mpaghara natara (ya bụ, akara VCO enwetara nke onye na-emepụta ugboro ugboro mepụtara), na-agbanwe akara ugboro dị elu ka ọ bụrụ akara ugboro dị n'etiti, wee quadrature na-ebelata mgbaàmà ahụ iji mepụta akara I na Q natara; Mgbe ahụ, a na-eme GMSK (Gaussian filter minimum frequency shift keying) demodulation iji gbanwee akara analog ka ọ bụrụ akara dijitalụ, wee ziga ya na ngalaba nhazi baseband.

Maka sekit nnyefe, akụkụ baseband na-eziga iyi data TDMA (na ọnụego nke 270.833kbit / s) maka modulation GSMK iji mepụta akara nnyefe I na Q, nke a na-eziga na transmission up converter maka modulation na transmission frequency band. Mgbe emechara ike, transmitter na-eziga ya site na antenna.

Ihe na-emepụta ugboro ugboro na-enye ihe mgbaàmà oscillator mpaghara dị mkpa maka mgbanwe ugboro ugboro maka nkeji nnyefe na nnata, ma na-eji teknụzụ mkpọchi nke usoro iji mee ka ugboro ugboro kwụsie ike. Ọ na-enweta ntụaka ugboro ugboro site na sekit ntụaka elekere.
