Abstract
An apparatus including an antenna and amplifier for receiving and amplifying a spread spectrum signal, at least two correlators for determining the correlation levels of the received signal with respect to the correlators corresponding code sequences, and a comparator for comparing the output levels of the two correlators. A signal detector is operably connect to the correlators for determining when a code sequence has been detected on one of the correlators. A phase-locked loop is controlled by the output of the signal detected unit and triggers a sample and hold device which samples the output of the comparator. A device is also provide to output the decoded data which is held on the sample and hold device.
