Embodiment Construction

[0017] The wireless channel feature detection system of the present invention is composed of two full-duplex communication nodes A and B, both of which have the functions of signal transmission and reception. The transmission of A and the reception of B are one frequency point, and the transmission of B and the reception of A are another frequency point.

[0018] A and B communication nodes have the same structure, and the system structure is as follows: figure 1 As shown, it includes a radio frequency module, an acquisition module, a timing module, a central computing module and a memory.

[0019] When the system is working, two nodes, A and B, send standard signals to shake hands with each other, and start to collect signals from each other at the same time, extract the baseband signal envelopes and store them in their respective memories. The communication node transmits the signal envelope to the central computing module through the data line for calculation, and obtains ...

Abstract

The invention discloses a wireless channel characteristic detection system. The wireless channel characteristic detection system comprises a full-duplex communication node A and a full-duplex communication node B with signal emitting and receiving functions, the signal emitting of the full-duplex communication node A and the signal receiving of the full-duplex communication node B use the same frequency point, and the signal receiving of the full-duplex communication node A and the signal emitting of the full-duplex communication node B use the other different frequency point. Each of the full-duplex communication node A and full-duplex communication node B comprises a radio frequency module, a gathering module, a time service module, a central computing module and a storage. The wireless channel characteristic detection system is capable of detecting the characteristics (intensity, phase and doppler frequency shift) of the wireless channel to provide technology support for symmetric key generation and distribution through using the wireless channel characteristics.

Description

technical field [0001] The invention belongs to the communication field and relates to a wireless channel feature detection system, which realizes the function of detecting received signal strength, phase and Doppler frequency shift from radio macroscopic features. Background technique [0002] With the development of radio communication technology, the security requirements in the communication process are getting higher and higher. By using the characteristics of the wireless channel to generate a symmetric key, the communication parties can generate and distribute a truly random and highly secure key in real time during the communication process. This method can be used in the wireless communication data link of missile weapons and on-orbit aircraft, which greatly improves the anti-interception capability of the data link. [0003] Since the existing communication system is not designed for the purpose of key generation, the existing communication system cannot detect th...
