Description

Technical Field

[0001] The present invention relates to the technical field of electronic communications, and particularly to an airborne shortwave communication system and method for simultaneous transmission of data and voice. Background Art

[0002] Current airborne shortwave communication devices all adopt a half-duplex communication mode, where the transmitting channel and the receiving channel have the same frequency. Although signals are allowed to be transmitted in two directions, at the same moment, they can only be transmitted in one direction. This means that both communication parties need to alternately send and receive data, and a set of shortwave devices can only perform voice or data communication services, and it is impossible to simultaneously implement two service transmissions on a set of devices.

[0003] In order to simultaneously transmit two services of voice and data, the common practice is to use two sets of radio stations operating at different frequencies to transmit voice and data respectively, without mutual interference. Due to the limited volume of the airborne platform, simultaneously deploying two sets of shortwave communication systems will introduce a series of problems such as increased weight, cost, and mutual interference. Therefore, it is of great significance to study a device that can achieve simultaneous transmission of data and voice through a set of shortwave radio stations. Summary of the Invention

Its working frequency is f v ; the data HF radio and the voice HF radio operate at different frequencies, that is, f d is not equal to f v ; the data and voice working modes of the data HF radio and the voice HF radio are controlled by the ground communication control system;
