Research algorithm of hide the speech messaging based on the spread spectrum method

Abstract

In the work the approach, which makes it possible to modify the method of expanding the spectrum for the realization of the reserved coding of voice communication in vocal data, is proposed. The results of investigating the dependence of different estimations on the values of the assigned parameters are represented. The development algorithm can make it possible to increase the effectiveness of the reserved exchange of voice communications, due to the more effective use of reticence and capacity of vocal material. The use of the orthonormalized basis instead of pseudorandom sequence, allows more effectively from the position of the volume of the coded information to use vocal material for the reserved transfer of communication.
