Embodiment Construction

[0040] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0041] Method example:

[0042] According to the Nyquist sampling theorem, when a DAC needs to be used to simultaneously generate multiple channels of different bandwidth signals, the sampling rate of the digital signal input to the DAC should be greater than twice the sum of the bandwidth occupied by all signals.

[0043] The signal input to the DAC is represented as:

[0044]

[0045] where S n is the baseband modulation of each signal, f n is the carrier frequency of the signal. Then the sampling rate requirements are as follows:

[0046] f s ≥2×(max(f n )-min(f n ))

Abstract

The invention relates to a baseband signal generation method and device, electronic equipment and a readable storage medium, belongs to the technical field of electronic countermeasure simulation training signal generation, and solves the problem of low baseband signal generation efficiency in the prior art. The method comprises the following steps: generating a plurality of alternative baseband sampling rates according to a final sampling rate; in the alternative baseband sampling rates, determining the baseband sampling rate corresponding to each signal feature according to the signal feature, and forming a baseband sampling group by the signals with the same baseband sampling rate; enabling each baseband sampling group to independently generate a signal. According to the technical scheme, the baseband signal generation efficiency is improved, and storage and communication resources are saved.

Description

technical field [0001] The present invention relates to the technical field of electronic countermeasure simulation training signal generation, in particular to a method, device, electronic equipment and readable storage medium for generating a baseband signal. Background technique [0002] Combat electronic countermeasure training such as electronic countermeasures troops, radar troops, and communication troops requires a complex electromagnetic environment. Therefore, training equipment that can generate a complex background electromagnetic environment is required, which is generally called an electromagnetic environment construction system. According to the actual combat training requirements of electronic countermeasures, the electromagnetic environment construction system needs to generate dozens of types of signals with an instantaneous frequency coverage bandwidth of more than 6 GHz, more than 400 channels at the same time, and independent configuration of each signal ...
