A METHOD FOR PERFORMING AN INCOMING SIGNAL CROSS-CORRELATION

摘要

According to the present invention, when a filter has a long length, like a finite impulse response filter, is used in a real-time system wherein a block size of a real-time input signal cannot be randomly determined, provided is a method to divide a front and a rear end of the filter into a plurality of blocks based on different manners to minimize a total amount of calculation.
