[0072] The understanding of inductive effects in physics has a long history. Physicists have proposed a variety of qualitative orders of induced effects based on the physical properties of electromagnetic waves, and also proposed a variety of fundamental amplitude characteristic constants in terms of quantitative relationships, but these fundamental amplitude characteristic constants are based on certain experimental data and according to the needs of calculations , specifying values ​​for each frequency one by one is for systematic analysis and research based on the frequency of multiple electromagnetic waves.

[0073] The signal-to-noise ratio gain is an important index to measure the effect of the FM gain system on enhancing and improving the input signal. Only when the SNR gain is greater than 1, can the FM gain system significantly enhance and improve the signal, and the SNR gain The larger the value, the better the detection effect. Assuming that the input signal is the ...

Abstract

The invention discloses a self-adjusting method for noise signals, which specifically includes: storing and preliminary processing of control signals and noise signals through a signal storage module; analyzing and comparing the control signals through the signal analysis module; according to step 2 The analysis and comparison results of the control signal are processed; through the signal induction module, the first induction signal and the noise signal undergo frequency modulation gain to generate an intermediate adjustment signal, and the intermediate adjustment signal and the processed control signal undergo secondary frequency modulation gain. output. A noise signal self-adjustment method provided in the present invention has strong versatility, and the method for verifying the noise reduction effect is relatively effective, and can effectively reduce the noise signal in the system link. It is different from the noise signal processing method in the prior art, that is, the noise signal is reused to control the frequency modulation gain of the signal, and provides a certain channel gain for system links such as communication and radar.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a self-regulating method for noise signals. Background technique [0002] In the prior art, wireless access radio frequency circuits are widely used to implement wireless connection and information exchange between devices. Microwave switches are the main part of communication and radar. In order to suppress the impact of noise at all levels on the system, the microwave switch needs a certain system gain, but too large gain will overload some modules in the microwave switch, resulting in nonlinear distortion. At the same time, the low noise amplifier in the microwave switch It is a small signal linear amplifier. Due to the influence of the transmission path, the strength of the signal changes. When receiving the signal, there is often strong interference. Therefore, the gain and attenuation need to be adjustable to obtain a larger linearity and dynamic range. [0003] In ...
