Tlhahlobo e tebileng ea melao-motheo ea ts'ebetso le ts'ebeliso ea li-duplexer, li-triplexer le li-quadplexer

Litsamaisong tsa puisano tsa waelese tsa sejoale-joale, li-duplexer, li-triplexer le li-quadplexer ke likarolo tsa bohlokoa tse sa sebetseng bakeng sa ho fihlella phetiso ea lets'oao la lihlopha tse ngata. Li kopanya kapa li arola matšoao ho lihlopha tse ngata tsa maqhubu, li lumella lisebelisoa ho fetisa le ho amohela lihlopha tse ngata tsa maqhubu ka nako e le 'ngoe ha li ntse li arolelana li-antenna. Ho sa tsotellehe phapang mabitsong le meahong, melao-motheo ea tsona ea motheo e tšoana, 'me phapang e kholo ke palo le ho rarahana ha lihlopha tsa maqhubu tse sebetsoang.

Duplexer

Duplexer e na le difilthara tse pedi tse arolelanang kou e tshwanang (hangata antenna) mme di sebediswa ho kenya tshebetsong mesebetsi ya phetiso (Tx) le ho amohela (Rx) sesebedisweng se le seng. E sebediswa haholo-holo ditsamaisong tsa karohano ya maqhubu a duplex (FDD) ho thibela tshitiso e tshwanang ka ho arola matshwao a phetiso le a amohelang. Duplexer e hloka boemo bo hodimo ba ho ikarola, hangata ka hodimo ho 55 dB, ho netefatsa hore letshwao le fetisoang ha le ame kutlwisiso ya moamoheli.

Triplexer

Triplexer e na le difilthara tse tharo tse arolelanang kou e le 'ngoe. E dumella sesebediswa ho sebetsana le matshwao a tswang dihlopheng tse tharo tse fapaneng tsa maqhubu ka nako e le 'ngoe mme hangata e sebediswa ditsamaisong tsa puisano tse hlokang ho tshehetsa dihlopheng tse ngata tsa maqhubu ka nako e le 'ngoe. Moralo wa triplexer o hloka ho netefatsa hore lebanta la ho fetisa la sefe ka seng ha le jarise difilthara tse ding mme le fane ka karohano e lekaneng ho thibela tshitiso e tshwanang pakeng tsa dihlopheng tsa maqhubu.

Quadplexer

Quadplexer e na le difilthara tse nne tse arolelanang kou e le nngwe. E dumella sesebediswa ho sebetsana le matshwao a tswang dihlopheng tse nne tse fapaneng tsa maqhubu ka nako e le nngwe mme e loketse ditsamaiso tse rarahaneng tsa puisano tse hlokang bokgoni bo phahameng ba spectral, jwalo ka theknoloji ya ho kopanya di-carrier. Bothata ba moralo wa quadplexer bo hodimo haholo mme bo hloka ho fihlela ditlhoko tse tiileng tsa ho ikarola ho netefatsa hore matshwao a pakeng tsa dihlopheng tsa maqhubu ha a sitisane.

Liphapang tse kholo

Palo ea lihlopha tsa maqhubu: Li-duplex li sebetsana le lihlopha tse peli tsa maqhubu, li-triplex li sebetsana le lihlopha tse tharo tsa maqhubu, 'me li-quadplex li sebetsana le lihlopha tse 'ne tsa maqhubu.

Ho rarahana ha moralo: Ha palo ea lihlopha tsa maqhubu e ntse e eketseha, ho rarahana ha moralo le litlhoko tsa ho itšehla thajana le tsona lia eketseha ka ho lekana.

Maemo a tshebediso: Di-duplexer hangata di sebediswa ditsamaisong tsa motheo tsa FDD, ha di-triplexer le di-quadplexer di sebediswa ditsamaisong tse tswetseng pele tsa puisano tse hlokang ho tshehetsa di-frequency band tse ngata ka nako e le nngwe.

Ho utloisisa mekhoa ea ho sebetsa le liphapang tsa li-duplexer, li-triplexer le li-quadplexer ho bohlokoa bakeng sa ho rala le ho ntlafatsa litsamaiso tsa puisano tse se nang mohala. Ho khetha mofuta o loketseng oa multiplexer ho ka ntlafatsa ts'ebeliso ea spectrum ea sistimi le boleng ba puisano ka katleho.
