Abstract：In this paper, the generalized orthogonal sequences and N-shift partial length D0 orthogonal sequences with partial correlations are investigated. In particular, the partial correlation properties of Loosely Synchronized (LS) sequences are analyzed in details. The results show that LS sequences have partial correlation orthogonal property at 4-shift with half length, which can be utilized to construct partial length auto-complementary sequences and even-shift partial length cross-complementary sequences. Multiple-access interference can be eliminated in synchronous Code Division Multiple Access(CDMA) systems if the N-shift partial length D0 sequences are adopted.
