  • Method and apparatus for synchronizing a plurality of code division multiple access signals to enable acquisition and tracking based upon a single pseudonoise spreading code
    Patent number: 5689526
    Abstract: A method and apparatus at a transmitter (800) initializes (904) pseudonoise (PN) sequence generators (302, 306, 320) to predetermined initial states and thereafter generates (906) time-synchronized PN sequences. A spread spectrum signal is then transmitted (908) by utilizing the PN sequences to encode information. At a receiver (600, 700) a predetermined one of the PN sequences is acquired and tracked (1002), and one of the predetermined initial states is predicted and tracked (1004). A PN sequence generator (608, 714, 722, 730) of the receiver is adjusted (1006, 1014) to generate a selected PN sequence time-synchronized with the predetermined one, and a corresponding one of the PN sequences is despread (1008) by utilizing the selected PN sequence to decode the information.
