abstract : in this paper, an orthogonal multicode wideband cdma system modelincluding pilot channel based on chaos spreading sequences is given . based on chaos sequences, with pilot channel inserted orthogonally, it is shown that the performance of the system is improved . the performance of the system in fading channel is analyzed 文摘:提出一種基于混沌序列含導(dǎo)頻信號的寬帶正交多碼cdma系統(tǒng)模型,利用混沌序列以及采用正交插入導(dǎo)頻信號提高系統(tǒng)性能,并對此模型在衰落信道中的性能進(jìn)行分析。
