Abstract

The invention discloses a continuous spectrum random signal carrier communication method, which comprises the following steps of: enabling a noise source to generate white noise, and converting the white noise into broadband noise in a preset frequency band by adopting a band-pass filter; amplifying the broadband noise by using an operational amplifier, and modulating the amplified broadband noise by using an information source to obtain a signal with information; processing the signal with the information through a detector to obtain an initial voltage signal; and offsetting noise in the initial voltage signal by adopting a multi-stage cascade circuit of a subtracter and an operational amplifier to obtain and output a final voltage signal. According to the method, spectrum resources are fully utilized through a continuous spectrum carrier modulation mode, a communication system with ultra-low power spectrum density is achieved, and the power spectrum density is lower than that of bottom noise, namely, the signal-to-noise ratio is lower than 1.

Description

technical field [0001] The invention relates to the technical field of carrier communication, in particular to a continuous frequency spectrum random signal carrier communication method. Background technique [0002] In the current wireless communication system, if the baseband source signal is not modulated, its frequency is very low and cannot be transmitted wirelessly. Therefore, it is necessary to modulate the carrier with the baseband signal to move it to the radio frequency spectrum of the carrier for wireless transmission. According to the different forms of the carrier, the modulation method of the communication system can be divided into continuous wave modulation and pulse modulation. These two modulation methods use sine-cosine continuous wave and digital pulse wave as the carrier respectively. [0003] The continuous wave modulation technology transmits information by controlling the amplitude, frequency, and phase of the carrier wave through the source signal. T...
