Abstract :
The security of the information is very important for wireless communication system, and chaotic radio modulation can provide new protection for the information. A bandpass chaotic signal design method is introduced to restrain the DC and the spectrum components in the low frequency of the chaotic signal which can be used as the radio carrier for the chaotic modulation. The N + 1 dimensions system is deduced from an N dimensions system, the output signal of which is added an integral to its derivative. The characteristic of the original system is kept and the purpose is realized by analysis and simulation. This new kind of signal will be suitable for wireless communication systems.
