Synopsis

Speech Scrambling technique is implemented on the TMS320C671 DSK and LabVIEW as a research work. The approach for TMS320C671 DSK makes use of algorithms for filtering and modulation. With voice as input, the resulting DSK output is scrambled voice. For the Descrambled output, output from the DSK is input to the another DSK and output is original analogue Signal. The research work involves the acquisition of voice data which is analogue in nature, its manipulation (Scrambling) before transmission in a manner which would secure its transfer through the communication channel, and finally retrieval of the actual Signal at the received end having appreciable quality. It is based primarily on the application of Electronics and Digital Signal Processing knowledge. Scrambling has been implemented in Frequency Domain using the Frequency Inversion. Apart from the hardware aspect of the project involving the use of filters, mixers, power Supplies, all combined in a Single circuit known as the DSP Kit TMS320C6711. It also requires Software knowledge Skills for C/C++ language programming and LabVIEW, in order to implement certain scrambling techniques.
