Hoʻolauna

I ka hoʻouna uila, ua hoʻokaʻawale ʻia ka Transmitter (Tx) a me ka Receiver (Rx) e kahi mamao a hoʻokaʻawale ʻia e ka uila. ʻOiai ua hoʻopaʻa ʻia ʻo Tx a me Rx i ka alapine like, aia kahi alapine offset ma waena o nā alapine lawe ma muli o ka ʻokoʻa ppm ma waena o nā oscillators i hoʻohana ʻia ma Tx a me Rx. Hoʻopaʻi ʻia ke alapine offset ma o ka hoʻohana ʻana i nā ʻano hana hoʻonohonoho hoʻonohonoho ʻikepili a i ʻole nā ​​​​ʻano hana hoʻonohonoho ʻike ʻole (makapō).

ʻO Costas Loop kahi ala PLL i kōkua ʻole i ka ʻikepili no ka uku hoʻopiʻi hoʻihoʻi. ʻO ka noi mua o nā loops Costas i nā mea hoʻokipa uila. Ma ka hoʻohana ʻana i kēia, ua uku ʻia ke alapine o ka offset ma waena o ka Tx a me Rx me ke kōkua ʻole o nā leo pilote a i ʻole nā ​​hōʻailona. Hoʻokomo ʻia ka Costas Loop no ka modulations BPSK a me QPSK me ka hoʻololi ʻana i ka poloka helu kuhi hewa. ʻO ka hoʻohana ʻana i kahi Costas Loop no ka ʻāpana a i ʻole ka hoʻonohonoho pinepine ʻana e hopena paha i ka ʻano ambiguity, pono e hoʻoponopono ʻia ma o nā ʻenehana e like me ka hoʻopili ʻokoʻa.

Hōʻuluʻulu manaʻo

Hāʻawi ka papa ma lalo i kahi hōʻuluʻulu o nā hiʻohiʻona Costas Loop.

Papa 1. Nā hiʻohiʻona Costas Loop

Manaʻo kumu Pili kēia palapala iā Costas Loop v1.0.
Nā ʻohana mea i kākoʻo ʻia
  • Polar Fire® SoC
  • Ke ahi polar
Kākoʻo ʻia Mea hana Kahe Pono ʻo Libero® SoC v12.0 a i ʻole nā ​​hoʻokuʻu hope.
Laikini ʻO Costas Loop IP maopopo ua paʻa ka laikini RTL a loaʻa manuahi ka RTL i hoʻopili ʻia me kekahi laikini Libero. RTL i hoʻopunipuni ʻia: Hāʻawi ʻia ke code RTL i hoʻopili piha ʻia no ke kumu, e hiki ai i ke kumu ke hoʻomaka koke me ka Smart Design. Hiki ke hana ʻia ka Simulation, Synthesis, a me Layout me ka polokalamu Libero. Holoi RTL: Hāʻawi ʻia ka code kumu RTL piha no nā papa kuhikuhi a me ka hoʻāʻo.

Nā hiʻohiʻona

Loaʻa iā Costas Loop nā hiʻohiʻona nui:

  • Kākoʻo i ka modulations BPSK a me QPSK
  • Nā ʻāpana hoʻohālikelike hoʻoheheʻe no ka laula alapine ākea

Ka hoʻokō ʻana o IP Core ma Libero® Design Suite
Pono e hoʻokomo ʻia ka IP core i ka IP Catalog o ka polokalamu Libero SoC. Hoʻokomo ʻia kēia ma o ka IP
ʻO ka hana hōʻano hou Catalog ma ka polokalamu Libero SoC, a i ʻole ke kiʻi lima ʻana o ka IP core mai ka catalog. Pākahi
ua hoʻokomo ʻia ka IP core i loko o ka Libero SoC software IP Catalog, ua hoʻonohonoho ʻia ke kumu, hana ʻia, a hoʻokomo koke ʻia i loko o ka hāmeʻa Smart Design no ka hoʻokomo ʻana i ka papa inoa papahana Libero.
