Abstract
We propose a new scheme for rapid acquisition of PN
signals in direct-sequence spread spectrum (DS/SS) systems by estimating
the phase of the received PN signal with the use of an auxiliary
signal. The auxiliary signal can be generated by a sum of the
phase shifted PN signals. The phase of the incoming PN signal is
estimated using the properties of cross correlation between the PN
signal and the auxiliary signal. True phase alignment is detected
using a conventional serial search scheme, where the initial phase
of the local PN generators is set to a value obtained by the phase
estimator. The performance of the proposed acquisition scheme is
analytically evaluated in terms of the mean acquisition time. Numerical
results show that the proposed scheme can achieve acquisition
at least two times faster than the conventional scheme in nominal
operating condition.
