摘要
跳频地址码的性能对跳频多址通信系统的性能起着关键性的作用。把混沌系统引入跳频通信系统可以得到大量性能良好的跳频地址码 ,但是数字计算中的有限精度效应会使混沌系统的性质恶化。这里提出以m序列扰动在双精度计算条件下产生跳频多址序列 ,对序列的性质进行了研究。
The characters of frequency-hopping multiple access (FHMA) codes have much effect on the performance of FHMA systems. Chaotic map sequences can be used as FHMA for their unique features. However, the precision-limited effect in calculating the sequences may ruin the features. We present in this paper a set of m-sequence disturbing chaotic map sequences obtained from a double-precision system, and the character of them.
