Furthermore, an implementable device is provided. The invention can be applied to signal processing, communication system and large-scale integrated circuit test and so on.

Description

technical field [0001] The invention belongs to the technical field of communication systems, and in particular relates to a signal generation method and device for generating a type two binary non-periodic Z complementary sequence pair by a deletion method. Background technique [0002] The two-type binary aperiodic Z-complementary sequence pair is composed of two sequences of equal length N, and its characteristic is that the sum of the aperiodic autocorrelation functions of these two sequences is at the maximum time shift point, that is, around τ=N-1 There is a zero correlation zone (ZCZ for short). For example, the following pair of binary sequences of length N=11: [0003] a =(1,-1,-1,1,-1,-1,1,-1,-1,-1,1) [0004] b The sum of the aperiodic autocorrelation function of =(1,-1,-1,-1,-1,-1,-1,-1,1,1,-1) is: [0005] (22,2,-2,6,2,-2,0,0,0,0,0) (0 ≤ time shift τ ≤ 10). [0006] It is very obvious that there are 5 zeros around the maximum time shift point τ=10, that is...

AI Technical Summary

Problems solved by technology

[0010] In short, in the prior art, there are few construction methods for the two-type binary aperiodic Z-complementary sequence pair, and they cannot generate all the required lengths, and cannot realize the adjustable width of the zero correlation zone. The construction process is relatively complicated, and the realization process is relatively difficult, etc. shortcoming
