Method for determining comb spectrum interference signal frequency points in multiple limited bandwidth ranges

Abstract

The invention provides a method for determining frequency points of comb spectrum interference signals in a plurality of limited bandwidth ranges, and the method comprises the following steps: generating comb spectrums with different frequency intervals based on different limited bands in a targeted manner, and calculating the maximum number of the comb spectrums which can be inserted into a certain limited bandwidth; obtaining the insertion frequency point of each comb spectrum based on the ratio of the maximum number of the comb spectrums which can be inserted to the number of the comb spectrums which need to be inserted actually, so accurate interference is generated on different working frequency points of different frequency bands. According to the method, the maximum number of the comb spectrums which can be inserted into a certain limited bandwidth is calculated, and the insertion frequency point of each comb spectrum is obtained based on the ratio of the maximum number of the comb spectrums which can be inserted into the limited bandwidth to the number of the comb spectrums which actually need to be inserted into the limited bandwidth, so accurate interference is generated on different working frequency points of different frequency bands, and conflicts between a plurality of limited bandwidth ranges and the total comb spectrum bandwidth are avoided.

Problems solved by technology

[0003] The current methods for determining the frequency points of comb spectrum interference signals in a limited bandwidth range are mainly based on the direct average division of the working frequency band, and the insertion of comb spectrum interference signals at the division points. Although these solutions are simple and direct, they lack the same The relationship between the bandwidth of the interference signal, especially when the bandwidth of the comb spectrum interference signal is large, inserting the comb spectrum interference signal at the split point will conflict with the working bandwidth range. To determine the accuracy of frequency points of comb spectrum interference signals, it is necessary to propose a new method for determining the frequency points of comb spectrum interference signals within a limited bandwidth range.
