Abstract

Secure Communication has always been placed on highest priority in civil and military communication systems. In such systems speech scrambling and descrambling techniques played a vital role for the ages. For these purposes scrambling could be employed in time domain well as in frequency domain. Further, security also demands for fast implementation. Lower the implementation time higher will be the level of security. In this regard, Texas Instruments has devised Digital Signal Processor based on a special architecture. This paper describes the Real-time implementation of frequency domain speech scrambling/descrambling technique (Frequency Inversion). First this technique is implemented in C language. Subsequently, the code is implemented on Texas Instruments’ DSP TMS320C6711 DSK. This work involves advanced filtering and optimizing techniques.
