Bidirectional NLOS Wireless Receiver 8MHz Telecommunication

Bidirectional video+data NLOS wireless telecommunication transceiver

SFGT-TD1400

The model DS-TD1400 TDD-COFDM transceiver is our new NLOS(non-line of sight) two-way data transmission system and wireless mobile emergency communication private network,which is independent of telecom operators wireless network.Its confidentiality,security,mobile performance that is better than Telecom operators.Also is a fully transparent data encryption transmission emergency security network.

TDDCOFDM multiplexing technology to channel resources in time through time slot, frequency through a large number of sub carriers to flexibly allocated to multiple users,and in a single frequency to maximize the realization of multi user access.Channel into the AES128bit ,and user defined-code that strength to ensure the data encryption.System occupy relatively narrow-band air frequency(4/8MHz)and strong anti-multipath interference ability to overome simulation technique and the high-speed mobile data transmission under multipath reflections and nuisance caused by occlusion,then achieved in a complex environment transfer: data packing form, audio and video data and serial asynchronous data.Its miniature volume, precision design, lightweight and easy to carry that commonly used in short distance high speed wireless data transmission and in sky long distance high speed wireless data transmission purposes.1) Such as special transmission: for any different size of drones,UAV, rotorcraft, UGV, gyroplane,unmanned parachute,unmanned submarine,unmanned boat,airship,high speed rail,motor car,unmanned robot etc..2)On ground station such as:short-range NLOS operations or LOS environment motion wireless communication.

Highlights:

1. Advancement:TDD-COFDM technology,with fast-moving,ultra-wideband, and fully transparent transmission.

2. Security: private network, private transport protocol, sole synchronization code and AES encryption.

3. Flexibility: transparent transmission of IP data channel, supports multi-user access.

4. Scalability: all-digital network, is compatible with all IP data transmission equipment.

5.Technical performance:

1) Multi-frequency network base stations,single base station same frequency network, the same frequency network with bidirectional communication, high spectrum efficiency;

2) Flexible allocation of channel resources to achieve PTP,PTMT and multipoint-to-multipoint two-way communication;

3) Multiple channel bandwidth and a variety of modulation mode function;

4) Flexible TDD slot allocation model to meet a single-frequency but multi-user access, not only save the spectrum but also to reduce power consumption;

5) Spectrum sensing, perception slot, upstream bandwidth sensing function;

6) Strong diffraction ability and anti-multipath capability

7) High-sensitivity receiver.When receive level is -110dBm, can still ensure BER <10E-5 and frame error rate <1%. Powerful error correction capability;

8)Low PAPR, high power amplifier efficiency, low power consumption;

9) Can transmit video audio and etc signals synchronous,high speed.Velocity >600km/h.

10)Digital signal processing, a strong system of confidentiality, stability and reliability.
