| Abstract: | This paper presents a study of a new sequences obtained from the changed model sequences, so as to improve the secrecy in communications. The related performances and power spectrum of the changed model sequences are discussed. The new sequences can be used as the scramblers and descramblers in digital microwave communications as well as optical fiber, satellite and mobile communications. Finally, two kinds of the changed model generators and of the scramblers and descramblers illustrated by the examples in digital microwave communication and digital mobile communication. |
