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 performance of frequency hopping address codes plays a key role in the performance of frequency hopping multiple access communication systems. The introduction of chaos system to frequency hopping communication system can get a lot of good performance of frequency hopping address codes, but the numerical accuracy of the finite precision of the chaotic system will deteriorate the nature of the system. It is proposed here that the m-sequence perturbation produces a frequency-hopping multiple access sequence under the condition of double-precision calculation, and the properties of the sequence are studied.
