Abstract :
An adaptive hybrid scheme for pseudonoise code acquisition is presented for DS/SS communications. The basic idea of the scheme is to utilise the correlator outputs for estimating the background power level and apply the constant false alarm rate (CFAR) technique to our scheme. Some examples of CFAR design are given and their detection performances are compared
