A Direct Sequence Spread Spectrum Transceiver with Enhanced Security Using Chaotic and Gold Sequence
Rahul Gupta, S. Anuradha · 2018
There is always a need and scope to enhance the security of wireless communication when radar and navigation applications come into picture. In this area, CDMA has contributed to its peak but not saturated. Different sequences have been used for the same. But better results have been observed with optimized chaotic sequences. This paper aims at amplifying the security aspect by using a combination of both chaotic sequence and gold codes along with real time implementation of the proposed system on WARP board. Also, an attempt has been made to extend the same system for multiple users and analyze system performance.
