Title Proper : ADAPTIVE ALGORITHM FOR OBTAINING IN-PHASE (I) AND QUADRATURE-PHASE (Q) PSEUDO-NOISE (PN) SEQUENCES IN CDMA SYSTEMS

Abstract : In the CDMA wireless systems, the forward pilot channel is spread in quadraturespreading. The quadrature spreading is a spreading sequence of length 215 pseudo-noise(PN) chips. For spreading rate (SR) 1, each PN chip is about 0.813ms. This sequence iscalled the pilot PN sequence and consist of a pair of PN sequences called the In-phase (I)and quadrature-phase (Q) sequences generated by a Linear Feedback Shift Register(LFSR). This pair of PN sequences is used to spread the forward and the reverse CDMAChannel. During the forward Pilot and Sync channel processing, the mobile stationacquires and synchronizes to the CDMA system while it is in the initialization state.
