Abstract :
Based on Chaos theory, a new hybrid chaotic frequency hopping sequence generation method is proposed, which combines Tent Chaotic Mapping with improved Logistic, then exclusive OR with balanced gold sequence .This sequencing will benefit the system with aspects such as the high system sensitivity to its initial conditions, sufficient amount of reproducible non correlation pseudo random. Simulations were done by MATLAB to study the performances of the new hybrid Chaos Frequency Hopping Sequence, which included the balance, correlation, sensitivity to initial conditions. The results show the new sequence is superior to the existing combined chaos frequency hopping sequence (Exclusive or of logistic sequence and m-sequence).
