The parallel combinatorial spread spectrum provides high spectral efficiency and the data rate of the parallel combinatorial spread spectrum is higher than that of the direct sequence spread spectrum. this thesis studies on the mapping between data and spread sequence in the parallel combinatorial spread spectrum system and presents a mapping method based on the lexicographic order. the mapping method resolves the many to one mapping problem of the past method
本文研究了并行組合擴頻中數據和擴頻序列之間的映射方法，指出了已有的一種不定方程求解演算法中存在的映射不唯一問題，應用組合數學中的相關理論，將映射問題轉化為廠組合問題，提出了基於字典順序的并行組合擴頻數據映射演算法，該演算法具有普遍性，解決了原有演算法中的多一映射問題。
