Abstract
Conventional Pseudorandom signals are used for spreading of signals in wireless communication. Due to increase gain of the system the code word length need to increase but due to practical limitation and increase in complexity chaotic signals can be use as alternative to pseudorandom codes for spreading of signals. A signal masking technique based on Lorentz System is presented in this paper which uses Lorentz equation generated Chaotic Signals are used as a encryption signal by which the basic digital modulated signal is mixed at the transmitter system. The scheme recovers the information signal exactly by synchronization at receiver. The mixing property of the implemented scheme investigated by Computer Simulations showing better security performance than that of the conventional method.
