  Abstract

This paper covers the detection of covert direct sequence spread spectrum signal without the PN(Pseudo Noise) code information Due to its low probability of interception, the difficulty of spectrum surveillance increases, Detection parameters are the signal existence of given bandwidth, the length of spreading sequence used by transmitter, and the identification of spreading code for detected chip length The tuple correlation function(TCF) value which is one of the higher order statistical signal processing technique can be used to detect spread spectrum signal without a prior knowledge, but, it has weakness that TCF results depend on the spread data sequence in actual application This paper proposes the new "scheme that not only overcomes the weakness but also presents better performance than the traditional TCF scheme The performance comparison of conventional TCF with proposed technique shows that the tripe correlation estimator(TCE) has better detection capability.
