Abstract

The invention discloses a multifunctional communication waveform generation method comprising the following steps of S1, randomly selecting starting frequency within a work frequency range of a multifunctional communication waveform, and generating a narrowband linear modulation waveform; S2, generating Gaussian white noise; S3, processing the generated Gaussian white noise by using a wideband band-pass filter to generate colored Gaussian noise; S4, modulating frequency of a sinusoidal wave by using the colored Gaussian noise, and generating a wideband noise frequency-modulated waveform; and S5, combining the narrowband linear modulation waveform generated in the step S1 with the wideband noise frequency-modulated waveform generated in the step S4 in a time domain to generate the multifunctional communication waveform. According to the method provided by the invention, the communication waveform part adopts the narrowband linear modulation waveform, and a central frequency point of a narrowband communication signal is randomly generated, so that the characteristic of being multifunctional is provided; the communication waveform is hidden in the noise waveform, so that hiding performance of the communication waveform is improved, and more safety and reliability during a signal communication process are ensured.

Description

technical field [0001] The invention belongs to the technical field of waveform generation, and relates to a multifunctional communication waveform generation method. Background technique [0002] In actual communication, the security and multi-mode features of communication are what all parties want to ensure. How to ensure the security, reliability and realization of multiple functions of communication based on the existing technical system and framework is a difficult problem in the field of communication. Commonly used methods in communication include frequency hopping communication technology and secure communication technology. Frequency hopping communication technology is widely used in multi-function communication. Since the signal-to-noise ratio is required at the receiving end, the frequency spectrum of the frequency-hopping signal can be clearly seen on the spectrum analyzer, and there are problems in multi-function communication. Secure communication technology ...
