| Abstract: | This paper deals with the design technique of multiple phase coded waveforms to counter the deception jamming of the distance.The performance analysis of the orthogonal waveforms,designed by traditional Genetic algorithm,is made.And based on this,the waveform-hopped transmission sequence for anti-jamming is designed.As the original signal has been intercepted,another one among the orthogonal waveforms is transmitted randomly.The performance analysis and simulations demonstrate the feasibility and validity o... |
