Abstract:
A fast-synchronizing receiver for receiving a spread-spectrum input signal comprising:equalizer means for correcting deficiencies in an input signal; despreader means in operational connection with said equalizer means for converting said spread-spectrum input signal to baseband form; synchronization means in operational connection with said despreader means for determining the start of said spread-spectrum input signal; and decoder means in operational connection with said despreader means for determining the contents of said spread-spectrum input signal, wherein said synchronizing means comprises: a plurality of incoming shift registers adapted to store a plurality of chips from an incoming signal; loading means for sequentially loading said incoming shift registers with chips of an incoming signal; predicting means in operable connection with said plurality of shift registers for predicting the next chip to be loaded by said loading means; and comparing means for comparing said predicting means with the chip loaded by said loading means; completion means in operable connection with said comparing means for determining when a predetermined number of consecutive number of comparisons agree.
