On almost perfect punctured binary sequence pair

This paper proposes a completely new periodic correlation signal-almost perfect punctured binary sequence pair (APPBSP). We present the definitions of APPBSP and its transformation properties. To reduce the searching range and improve the searching efficiency of APPBSP, limited conditions of APPBSP are discussed to decide the punctured locations within the sequence pair. Searching results of APPBSP with length no more than 20 show that high energy efficiency can be achieved at APPBSP length 5, 9, 10, 11, 12, 13 and 16, Such high energy efficiency APPBSP is feasible for engineering applications as synchronization codes and multi-user codes.
