Complex baseband signal reconstruction processing method and device

Abstract

The invention discloses a complex baseband signal reconstruction processing method and device. The method comprises the following steps: interactive control of a digital baseband data generation module, a multi-stage interpolation filter, an N-phase DUC component, an N-phase signal combining component and a D / A conversion component is realized by adopting a reconstruction control module, and the system is enabled to achieve complex baseband signal reconstruction processing by receiving an external user instruction and then controlling the corresponding components; and the digital baseband datageneration module generates data with a specified symbol rate, the data is up-sampled to a system clock frequency through the multi-stage interpolation filter, the N-phase DUC assembly interpolates the up-sampled data to obtain N paths of parallel baseband signals, the N paths of baseband signals are combined by the N-phase signal combining assembly and then output to the D / A conversion assembly,and the D / A conversion assembly converts the signals into analog signals and outputs the analog signals. All filter coefficients can be configured by a user, corresponding parameters can be configured as required, and dynamic configuration and reconstruction can be realized.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a complex baseband signal reconstruction processing method and device. Background technique [0002] The combat objects of electronic warfare equipment are the rapidly developing and changing enemy's electronic technology, military electronic systems and electronic weapons and equipment. The test and verification of electronic warfare equipment is particularly important to evaluate the electronic warfare capability and combat effectiveness of electronic warfare equipment. For the signal types of the complex CNI (communication, navigation, identification) signal environment on the battlefield, it mainly includes satellite communication signals, tactical communication signals, data link signals, navigation signals, and identification signals. For electronic warfare equipment, there is a large amount of multi-source interactive information inside the CNI system, which is ...

AI Technical Summary

Problems solved by technology

[0003] The implementation of digital baseband signals at this stage can only be aimed at specific types of baseband signals, and users cannot implement dynamic configuration, and the channel is exclusive

All coefficients cannot be configured by users, and corresponding parameters cannot be configured according to needs, let alone dynamic configuration reconstruction.
