Problems solved by technology
[0006] The above process mainly puts the up and down conversion program and the direct sampling program together, and transmits through the low-speed interface. These data interfaces are susceptible to high-frequency interference, and when multi-channel design is carried out, the transmission of multiple low-speed interfaces will also cause data transmission. Unstable; and from the perspective of the program, because the program takes up too much resources, it will cause the device to heat up and cause the device to be abnormal

The invention discloses a general platform for direct acquisition of radio frequency for short-wave communication based on localization. The attenuator, the first amplifier, the first filter, the first transformer and the analog-to-digital converter; the radio frequency transmitting module includes the digital-to-analog converter, the second transformer, the second amplifier and the second filter which are connected in sequence. The invention places the multi-channel part in the direct sampling part, and transmits at high speed through 3.125G optical fiber, so that the optical fiber transmission has higher stability and is not easily affected; and separates the direct sampling program and the up-down conversion program to reduce the resource occupation of the chip.
Description
technical field [0001] The invention belongs to the technical field of short-wave communication systems, and in particular relates to a general platform for direct acquisition of radio frequency for short-wave communication based on localization. Background technique [0002] At present, the core components of the existing shortwave radio are imported chips, and the performance indicators of domestic chips cannot meet the requirements for use. The imported chip adopts a low-speed baseband interface in data transmission, and after sampling the short-wave signal, the optical signal is directly transmitted to the signal processing unit for up-conversion processing. [0003] The existing imported chips adopt the general platform of radio frequency digitalization (hereinafter referred to as the radio frequency digitalization module). The main work flow is as follows: [0004] Receive signal process: The signal received from the power amplifier is processed by the front-end of th...
