Analyzing The Balance Performance Of Novel Oversampled Chaotic Spreading Spectrum Sequence

As several typical chaotic maps have been adopted in spread spectrum communication, it makes reconstruction of these chaotic sequences easy and reduces security of communication system. The oversampled chaotic map spreading spectrum sequences are proposed. The relationship among the performance of balance and oversampled parameter, initial value and the period of sequence are analyzed. The experimental results are shown that the oversampled chaotic map sequences have good performance of security of communication systems and optimal balance. The non-balanced points, which should be avoided in this paper using chaotic sequences, can meet the demand of DS/CDMA communication system when sequence length is over 1000.
