In this dissertation, the researches on the application of cdma in fiber - optic communication systems have been reviewed, and several key techniques in the application are proposed with theoretical analysis. in traditional researches and applications of the hfc cdma communication system, the gold sequence was used as the users " address code. in this paper, we analyze the characteristics of the m sequence in detail
本文突破了以往在hfc系統中使用cdma擴頻技術通信時，通常都採用gold序列來作為地址碼的慣例，分析和提出了在hfc的特定環境中，使用同一m序列在某時刻具有的不同相移序列，來構成一個小區的地址編碼，能夠達到多用戶通信時比使用gold序列進行通信具有更好的相關特性。Traditional multiuser detector make good use of all signals which resuilt in multiple access interference so that it provides optimum mai resistance. ( 1 ) nevertheless, it assumes that the receiver can acquire the signature waveform and timing of desired user and the interfering users ; ( 2 ) it has no ability to suppress intercell multiple access interference ; ( 3 ) it cannot be applied in downlink channels. adaptive multiuser detector eliminates the need to know the signature waveforms and the timing of the interferes and has to need training data sequences for every active user
