Abstract
Since all PN sequences used in practical DSSS systems are periodic and have finite length, this paper proves that the result sequence of CW interference being despreaded varies according to sinusoid in time, its frequency and amplitude are derived, and two special cases are discussed. Simulation and practical system verification also show the validity of results.
