Abstract A new concept of orthogonal matrix pair is presented, which is the extension of orthogonal matrix, and especially the binary orthogonal matrix pair is not restricted by the fact that the order of matrix should be the power of 2. Based on the binary sequence pair with two-level periodic autocorrelation, the binary orthogonal matrix pair and orthogonal sequence pair set are constructed. By interleaved technology, a new class of binary Zero Correlation Zone (ZCZ) sequence pair sets applied to Quasi-Synchronous Code Division Multiple Access (QS-CDMA) is constructed from the binary orthogonal matrix pair or orthogonal matrix and orthogonal sequence pair set. In order to achieve greater energy efficiency and upper theory bound of binary ZCZ sequence pair sets, it is necessary to select appropriate binary sequence pairs with two-level periodic autocorrelation.
