Abstract
An adaptive dummy spectrum insertion method which is applied to the asynchronous analogue-digital-analogue (ADA) speech scrambler is presented. Related analysis and computer simulation results are given. Both analysis and simulation results indicate that the method greatly improves the security of the scrambler, and maintains good speech quality.
