Abstract
Provided is an apparatus and method for detecting a code of a direct sequence spread spectrum signal obtained by spreading data in a direct sequence spread spectrum method with a predetermined code to despread the direct sequence spread spectrum signal. The apparatus includes an analog-digital (AD) converter, a serial-to-parallel converter, a triple correlator, a data dependency remover, and a mean value calculator. Herein, the code used for the spreading of the spread spectrum signal is detected by using a set of discrete time delay sequence pairs that the mean correlation function value outputted from the mean value calculator becomes a maximum.
