Abstract
A direct-sequence spread-spectrum communication system having a receiver that despreads a received signal that has been modulated with a pseudonoise code generated by a linear feedback shift register. The receiver despreads the received signal by multiplying it with a limited number of delayed replicas of the received signal. Despreading is thus performed without need for a locally generated pseudonoise code or a synchronizing clock.
