COFDM wireless receiver

COFDM wireless receiver nrog Long deb kis tau tus mob deb

system zoo

1. Ntev deb kis tau tus mob deb

2. Real-lub sij hawm kis tau tus mob system

3. Qeeb lub sij hawm yog heev luv luv tsawg tshaj li 500ms

4. Zoo meej cov duab zoo, qaim xim thiab cov duab smoothing

nta

1. Kis tau tus mob hwj chim 1W

2. Tsis tshua muaj neeg sib thiab rugged tsev nyob

3. kev co, tej yam kuj

4. Daim ntawv thov ntawm COFDM tes taws los piav, MPEG-2 / H.264 compression

5. loj me me, 102 tsuas × 60 × 21.5 hli

6. Zoo meej mobile daim ntawv thov

7. Video kis tau tus mob uas zoo, tsis muaj mosaic, tsis muaj luag tshwm sim

8. Kev them nyiaj yug uas tsis yog-line-of-pom kis tau tus mob, muaj zog diffraction muaj peev xwm ua;
