Acquisition of pseudonoise sequences in direct-sequence spread-spectrum systems
Abstract
dc:descriptionVarious schemes for the acquisition of a pseudonoise (PN) sequence in a baseband direct sequence spread-spectrum (DS/SS) system are investigated. First, we consider acquisition schemes for receivers with chip synchronization, that is, the chips of the transmitter and receiver PN sequence generator are synchronized, and only the starting point (or phase of the PN sequence) is unknown. Acquisition schemes for such receivers can be divided into active acquisition schemes, in which the receiver uses the observations to directly deduce the phase of the received sequence, and serial search schemes, in which the receiver guesses the possible phases in some predetermined order and uses the observations only to check if a particular guess is correct.
