The invention discloses a method for generating a simulation excitation source signal. The method includes: receiving an input simulation signal, and performing signal preprocessing on the input simulation signal; converting the input simulation signal to a first digital signal with a first preset sampling rate, and performing quadrature down-conversion and filter decimation processing on the first digital signal to obtain a second digital signal with a second preset sampling rate; writing the second digital signal in a memory in a data form; reading the second digital signal from the memory in the data form; and performing quadrature up-conversion and interpolation filtering processing on the second digital signal to obtain the simulation excitation source signal. Correspondingly, the invention also provides an apparatus for generating the simulation excitation source signal. According to the method and apparatus, various waveform characteristics of the original signal can be completely reserved, the completeness and the accuracy of a maintenance test are guaranteed, and the adaptability is high.
Description
Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and equipment for generating a simulation excitation source signal. Background technique [0002] With the continuous development of ultrashort wave communication technology, a large number of ultrashort wave digital radio stations are equipped with troops. Due to the technical system of ultra-short wave digital radio, such as baseband signal, signal coding, intermediate frequency modulation and other key content related to waveform characteristics belong to the core technology of the enterprise, radio equipment manufacturers do not disclose to the public due to the need to protect intellectual property rights, which makes it difficult for test equipment manufacturers to develop Excitation signal sources with the same technical system and consistent waveform characteristics make it difficult for maintenance personnel to perform equipment maintenance and can...
