METHOD AND SYSTEM FOR REDUCING SYNCHRONIZATION TIME IN A CDMA WIRELESS COMMUNICATION SYSTEM

摘要

A method and system for generating forward link channels in a synchronous CD MA base station having a pilot pseudonoise (PN) sequence with a pilot PN sequen ce offset. In one embodiment, the method includes the steps of generating a syn c channel (302) including a sync channel message; generating an identification channel including at least the pilot PN sequence offset; and orthogonalizing the sync channel and the identification channel. The identification channel and the sync channel are both transmitted. However, the mobile station may g et the pilot PN offset from the identification channel quickly, rather than having to demodulate the entire sync channel message. The identification channel may further include an indication of the phase of the pilot PN sequence, and the epoch of the pilot PN sequence. In one embodiment, the method includes encoding the identification channel using a Golay code.
