The uniqueness of punctured binary sequence pairs is proposed and proved. In particular, perfect punctured binary sequence pairs (PPBSP), almost perfect punctured binary sequence pairs (APPBSP), pseudorandom punctured binary sequence pairs(PRBPSP) and punctured binary sequence pairs with two-level autocorrelation(PBSPT) are proved as the specific cases of perfect punctured LCZ/ZCZ sequence pairs....
A perfect punctured binary sequence pairs (PPBSP) circular correlation based channel estimation algorithm for orthogonal frequency division multiplexing (OFDM) is proposed. The original sequence of PPBSP with cyclic prefix (CP) is inserted between OFDM symbols as training sequence. The cross-correlation is calculated between the received sequence with CP removed and the punctured sequence of PPBSP...
This paper proposes a completely new complementary sequence - complementary punctured binary sequence pair (CPBSP). We present the definitions of CPBSP and its transformation properties. To reduce the searching range and improve the searching efficiency of CPBSP, the limited conditions of CPBSP are discussed to decide the punctured locations within the sequence pair. Searching results of perfect CPBSP...
In this paper, the theory of perfect punctured ZCZ sequence pair sets is defined. The methods for constructing perfect punctured ZCZ sequence pair sets are based on the perfect punctured binary sequence pair and some matrices. A new frame, used in QS-CDMA or S-CDMA system which requires good periodic correlation functions of spectrum frequency codes, is presented and proved. The performance of perfect...
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...
