Abstract

The invention provides a method for determining the frequency points of comb spectrum interference signals within a plurality of limited bandwidth ranges. Comb spectra with different frequency intervals are targetedly generated based on different limited bandwidths. By calculating a certain limited bandwidth, the maximum comb spectrum can be inserted Number, based on the ratio of the maximum number of combs that can be inserted to the actual number of combs that need to be inserted, the insertion frequency point of each comb spectrum is obtained, thereby generating precise interference to different operating frequencies in different frequency bands. The present invention obtains the insertion frequency points of each comb spectrum based on the ratio of the maximum number of comb spectrums that can be inserted to the actual number of comb spectrums that need to be inserted by calculating the maximum number of comb spectrums that can be inserted in a certain limited bandwidth, so as to Different operating frequency points in different frequency bands generate precise interference, avoiding conflicts between multiple limited bandwidth ranges and the total comb spectrum bandwidth.

Description

Technical field

[0001] The present invention relates to mobile communications, digital signal processing and other related technical fields, in particular an interference frequency point estimation method. Background

[0002] In order to generate a comb spectrum interference signal for a digital receiver operating in a plurality of limited bandwidth ranges, in order to achieve targeted interference at one or more frequency points in the signal of different operating bandwidth bands, a method for determining the frequency points of comb spectrum interference signals in a plurality of limited bandwidth ranges is proposed. The technology is based on different finite bands to produce different frequency intervals of the comb spectrum, by calculating a limited bandwidth maximum number of comb spectrum can be inserted, based on the ratio of the maximum number of comb spectrum that can be inserted and the number of comb spectrum that actually needs to be inserted, the insertion frequenc...
