Abstract

See full text

A method and arrangement for calculating correlation between a first and second code sequence, which comprise a number of samples and have a finite length is disclosed. The arrangement comprises an assembly for estimating the delay between the code sequences and an assembly for setting the codes to a desired phase with respect to each other on the basis of the delay between the code sequences by rotating the first sequence. To allow correlation to be calculated quickly and simply, the arrangement includes an assembly for comparing the sequences with each other in parallel mode sample by sample and an assembly for adding the results of the sample-specific comparisons together.
