Problems solved by technology
Due to the influence of the environment, there will be multipath effects and inter-symbol interference. Since the speaker is also nonlinear, it will also bring nonlinear distortion to the communication signal.
These will cause distortion to the communication signal at the receiving end, and in severe cases, the audio communication system cannot work normally

Embodiment Construction
[0020] The technical solution in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] In the present invention, the term "module" generally refers to: hardware, a combination of hardware and software, software, and the like. For example, a module may be a process running on a processor, a processor, an object, an application executable, a thread of execution, a program, or the like. Both an application running on a processor and the processor may be modules. One or more modules can be localized on one computer and / or distributed between two or more computers.

The invention discloses an audio communication method and device, a communication device and a computer-readable storage medium. The audio communication method includes the following steps: receiving a first audio communication signal; providing the first audio communication signal to a distortion correction module, The distortion correction module is configured to perform distortion correction processing on the first audio communication signal to generate a second audio communication signal; output a first sound corresponding to the second audio communication signal through a speaker. The invention enables the audio receiving device at a relatively short distance from the loudspeaker to accurately restore the information transmitted by the audio communication device, and does not need to perform equalization processing on the received communication signal.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an audio communication method and device, a communication device, and a computer-readable storage medium. Background technique [0002] The wireless channel is a time-varying multipath fading channel. Multipath effect is the most important characteristic of wireless channel, and multipath effect will bring intersymbol interference. Intersymbol interference will deteriorate the received signal, thereby increasing the bit error rate and degrading system performance. In severe cases, the system cannot continue to work normally. [0003] For an audio communication system, the communication signal is transmitted through a loudspeaker at the transmitting end, transmitted through an air transmission channel, and received through a microphone at the receiving end. Due to the influence of the environment, there will be multipath effects and inter-symbol interference. Since...
