System description:
TDD Individual Standard Definition Twoway voice Wireless Video Transmission system adopting TDD twoway network transmission technology,on the basis of integration of the latest LTE mobile TDS and terrestrial digital TV technology features and advantages,independent research and development the design of new generation of Multiple access wireless communication technologies,adopts the most advanced code modulation in multi-user wireless communication field ,TDD-OFDM,LDPC error correction code,DPD,H.264 codec technology as the core,assigning channel resources through slot control, through the sub-carrier frequency flexibly assigned to multiple user terminals,within the same frequency maximized realized access multiple endusers multiple access. In the NLOS and high speed movement realize real-time two way transparent information transmission, Multiple wireless networks can be integrated with each other layout large network coverage.
System function and characteristics:
1. with strong diffraction ability,Support two-way communication in a single frequency, high frequency spectrum utilization;
Wide coverage, flexible allocation of channel resources, to achieve point to point, point to multipointk multipoint to multipoint two-way communication.
Strong ability of error correction,adopts world most advanced LDPC error correcting code technology,carrier to noise ratio threshold is 0.5dB under QPSK mode, approaching the theoretical limit communication.
Anti-fading ability, the system has a strong anti-fading; TDD two-way image transmission technology with respect to the single-carrier frequency domain equalization technology, inherently long delay and strong anti-multipath capability, more suitable for urban environments.
Video, audio, data and other multimedia information, high-speed, real-time, synchronous transmission.
Good mobility, moving faster than 200km / h.
Using the latest pre-distortion technology, will reduce the PAPR, improve power amplifier efficiency, TDD-OFDM mode allows the unit to open only in certain time slots, other times you can turn off standby to save power.
Using the unique encryption technology, digital signal processing, strong system security, stabilization and reliability.
Four network application architecture: a single center station, multi-center station, more remote stations (multiple access) and personal piggyback onboard remote terminal of the networking program.
Image quality: HD / SD / D1 / Half 720P optional.
