Abstract
Provided is a method for transmitting signals, including: acquiring a first image by performing a Fourier transform on first data to be transmitted; performing first preprocessing on the first image, wherein the first preprocessing comprises at least one of compression, encryption, or verification; acquiring second data by performing an inverse Fourier transform on the first image after the first preprocessing; and modulating the second data into a first radio frequency signal, and transmitting the first radio frequency signal.
Claims19
A method for transmitting signals, applied to a communication device comprising:
- a data processing module and a signal-transmitting assembly, the method comprising:
- acquiring, by the data processing module, a first image by performing a Fourier transform on first data to be transmitted;
- performing, by the data processing module, first preprocessing on the first image, wherein the first preprocessing comprises at least one of compression, encryption, or verification;
- acquiring, by the data processing module, second data by performing an inverse Fourier transform on the first image after the first preprocessing;
- and
- modulating, by the signal-transmitting assembly, the second data into a first radio frequency signal, and transmitting the first radio frequency signal,
- wherein the acquiring, by the data processing module, the first image by performing the Fourier transform on the first data to be transmitted comprises:
- acquiring, by the data processing module, a spectrogram of the first data by performing the Fourier transform on the first data to be transmitted, wherein the spectrogram of the first data is a graph of frequencies the first data over time;
- and
- determining, by the data processing module, a first coded image corresponding to the spectrogram as the first image based on a mapping relationship between spectrograms and coded images.
