The performances of different spreading sequences employed in spread spectrum communication systems have been investigated over removing from the spectrum of non-stationary jamming signals involved in the system in this paper. The performances of the PN, Barker and CCK spreading sequences, located in the IEEE standards, are analyzed comparatively in this work, inspired by the proposed method in [1], for the excision of jamming signals included in the system. Computer simulations have been performed for the different values of noise power and the jamming signal power, involved in the system. The obtained simulation results have demonstrated that the best performances are achieved with CCK spreading sequence in even high jammer to signal ratio (JSR) values.
