Abstract

The invention relates to a broadband shortwave digital radio station and a running method thereof. The broadband shortwave digital radio station comprises an audio processing module, an FBGA (Fine-pitch Ball Grid Array) processor, a wireless receiving-transmitting module, an interface module and an operation panel, wherein the audio processing module, the operation panel, the interface module and the wireless receiving-transmitting module are connected with the FBGA processor respectively; the interface module is connected with an external broadband; and the wireless receiving-transmitting module is wirelessly connected with an external receiving-transmitting device. Compared with the prior art, the broadband shortwave digital radio station has the advantages that the audio processing module, the FBGA processor, the wireless receiving-transmitting module, the interface module and the operation panel are operated in a coordination way, so that a single-sideband communication way and a broadband processing way can be realized simultaneously; single-direction digital directed transmission is adopted; and meanwhile, the FBGA processor can be used for adjusting a filtering range, thereby increasing the filtering accuracy and the filtering efficiency.

Description

technical field [0001] The invention relates to the technical field of radio stations, in particular to a broadband short-wave digital radio station and an operating method thereof. Background technique [0002] Shortwave radio refers to radio communication equipment with a working wavelength of 100 to 10 meters (frequency of 3 to 30 MHz). It is mainly used to transmit voice, constant amplitude report and frequency shift report. When transmitting telephone signals, amplitude modulation and single sideband modulation are used. It consists of transmitter, receiver, antenna, power supply and terminal equipment. It is generally divided into portable, vehicle-mounted, and fixed radios; it has the characteristics of small size and light weight, and usually uses a whip antenna, using ground waves for short-distance communication, and the power is usually several watts to hundreds of watts. There are still some defects in the radio station, such as application number 201520986622...
