Contributions in this paper mainly sh ow four points : 1 the structure characteristic of the received ds - cdma signal is analyzed in the presence of multi - path slow fading effect case for wireless mobile communication. according to this characteristic, four data - selected schemes based on chip - matched filter are presented from the perspective of energy and structure of signal. and the impact of these schemes on multiple - access interference ( mai ) and inter - symbol interference ( isi ) is analyzed
本文的主要貢獻在於四個方面: 1 、針對無線移動通信系統中廣泛存在多徑慢衰落效應的情況,分析了ds - cdma系統中接收信號本身的結構特徵,根據這個特徵,在匹配濾波的基礎上,從能量與信號結構的角度提出了四種不同的數據採用方案,並分析了不同數據方案對多址干擾與碼間干擾的影響。 -
The practical aspects of these multiple access techniques are also discussed and compared. the hybrid schemes, which combine the advantages of both orthogonal and non - orthogonal techniques, can provide promising solutions for future wireless cellular communications
我們討論和比較了這些接入方式在實際應用方面的因素,指出綜合正交和非正交方式優點的hybrid系統可能是未來無線蜂窩通信的一種可行方案。
