Abstract

The invention belongs to the technical field of super-regeneration receivers, and particularly relates to a novel super-regeneration receiver based on a super-regeneration chaotic oscillator and a use method thereof. The super-regeneration chaotic oscillator comprises a low-noise amplifier, a super-regeneration chaotic oscillator, a super-regeneration oscillator, an envelope detector, a low-pass filter and a judgment module, wherein the electrical output end of the low-noise amplifier is electrically connected with the super-regeneration chaotic oscillator, and the electrical output end of the super-regeneration chaotic oscillator is electrically connected with the super-regeneration oscillator. According to the novel super-regeneration receiver based on a super-regeneration chaotic oscillator and the use method thereof, the output signal of the super-regeneration chaotic oscillator is used as a secondary excitation source, detection and identification of a chaotic state are avoided, external periodic driving force is prevented from being added, and high-sensitivity receiving of a receiver can be realized by utilizing the insensitivity of the chaotic state to noise and the high response capability of the chaotic state to a weak periodic signal.

Description

technical field [0001] The invention relates to the technical field of super-regenerative receivers, in particular to a novel super-regenerative receiver based on a super-regenerative chaotic oscillator and a method for using the same. Background technique [0002] The architecture of the super-regenerative receiver was first proposed by Armstrong in 1922. Its simple structure and extremely low power consumption make it one of the earliest receiver technologies still in use today. It still has broad prospects and researches today. value. However, the super-regenerative receiver uses the amplitude modulation signal for detection, which uses the envelope difference between the OOK signal "0" and "1" input for detection, so the detection is limited by the noise level. Once the signal-to-noise ratio is too small, it will cause the signal The detection does not reach the predetermined threshold of the receiver, so that no useful signal can be received. [0003] The research on ...
