A novel approach for data transmission over voice dedicated channel of worldwide wireless telecommunication networks

In this paper, a novel approach for data transmission over voice channels (DoV) is presented. The usefulness of this approach stems from the fact that all wireless telecommunication networks have been basically designed to transfer speech and voice. We used this property to cope with the problem of transferring data over voice channels. In our approach, design of voice-like symbols is based on a search algorithm over hi-fi speech records. Using them, it is possible to transfer coded data over any desired voice channel as well as to gain more insight into its performance on privacy. We present methodology of our approach and also give the simulation results over some vocoders of GSM network.
