Abstract

The invention relates to a mass data correlation peak position fast obtaining method. The mass data correlation peak position fast obtaining method comprises a step 1 of re-sampling of data to be processed, a step 2 of correlation operation of samples of the re-sampled data, a step 3 of raw data interception, a step 4 of correlation operation of samples of the intercepted data, and a step 5 of calculation for obtaining correlation peak positions of raw data. The mass data correlation peak position fast obtaining method can solve the problems that in a common method, when mass data correlation peak positions are to be obtained, the number of operations is too large and the operation time is too long, thereby mitigating the adverse effect that a data processor needs to operate in an overloaded mode for a long time.

Description

technical field

[0001] The invention relates to a method for obtaining the correlation peak position, in particular to a method for quickly obtaining the correlation peak position of a large amount of data. Background technique

[0002] With the development of digital signal processing technology and the continuous improvement of data acquisition rate, the pressure of data volume and operation speed faced by the post-processor is increasing day by day. As one of the most commonly used methods in signal processing, correlation operation mainly involves multiplication and addition operations in essence, as shown in Equation 1.
