混沌扩频序列的多址性能分析

Multiple access performance evaluation for the chaotic spreading sequence

着重分析了混沌扩频序列在DS CDMA系统中的抗多址干扰性能 ,推导并定义了扩频通信系统的平均多址干扰指数W .通过与m序列及Gold序列进行比较 ,发现混沌扩频序列的平均多址干扰指数比它们更大 ,这表明混沌扩频序列的相关性能优于传统的伪随机扩频序列 .文中对

The multiple access performance evaluation for chaotic spreading sequences is analyzed theoretically. The W index as the standard to judge the performance of chaotic sequences and m sequence and Gold sequence is defined. By using W index, the performance of four sequences is compared. The simulation results show that the sequences generated by the Chebyshev map is the best.
