COFDM wireless receiver mamaʻo mo moʻoni – founga hono fakahū ʻo e taimí

COFDM wireless receiver

COFDM wireless receiver ʻoku mamaʻo ʻene feʻaveʻaki

 

 

Ngaahi lelei ʻo e polokalamá

 

1. Mamaʻo ʻene fetuʻutaki mamaʻó

2. Founga feʻaveʻaki taimi totonú

3. ʻOku siʻisiʻi ange ʻa e taimi fakatoloi ʻi he 500ms

4. Tu'unga lelei 'o e 'imisi haohaoa, ngaahi lanu fakaʻofoʻofá mo e ʻīmisí ʻoku hamolemole

 

Ngaahi fotunga

 

1. Mālohi feʻaveʻaki 1W

2. Nofoʻanga manifi mo tokakovi ʻaupito

3. tetetete, mālohi ʻo e fakafepaki

4. Ko hono fakaʻaongaʻi ʻo e coFDM, MPEG-2 / Lahi 'o e H.264

5. Lahi siʻisiʻi, 102 ko e × pe 60 × 21.5 MM

6. Tonu ʻa e mobile application

7. Feʻaveʻaki ʻo e vitioó ʻi ha tuʻunga māʻo, 'ikai ha Mosese, ʻikai ha tohoʻi fakaofo

8. Poupouʻi ʻa e feʻaveʻaki ʻoku ʻikai ko e ʻatá, malohi 'o e diffraction 'a e me'a 'e malava;
