The study of Low/Zero Correlation Zone sequence pairs spread spectrum communication system;

New class of ternary two dimensional array sets with a zero correlation zone;

Based on Hayashi s construction,a new approach to the construction of binary sequence set with zero correlation zone is presented by using ideal binary two level autocorrelation sequences and orthogonal sequences.

Based on perfect array pair and orthogonal matrix, ZCZ array pairs set with certain vol-ume, family size and zero correlation zone can be synthesized through row or column interleaved technique when suitable shift sequences are selected.

Research of ZCZ ternary sequence pairs set based on pseudorandom sequence

The perfect punctured array pairs are used in a zero correlation zone(ZCZ),and then a construction method for ZCZ array pairs set is presented.

Based on equidistant code, a method for obtaining spreading sequences with zero correlation zone (ZCZ) or low correlation zone (LCZ) is proposed, these spreading sequences can be employed in approximately synchronized code division multiple access (AS-CDMA) system to eliminating multiple access interference .
