Construction and Assignment of Orthogonal Sequences and Zero Correlation Zone Sequences Over GF(<i>p</i>)

Orthogonal sequences can be assigned to a regular tessellation of hexagonal cells, typical for synchronised code-division multiple-access (S-CDMA) systems. The within any cell should both orthogonal in the adjacent cells and require sufficient number users each cell. However, binary sequences, capacity communication system is limited. So, new family non-binary constructed, which has more per than network. Next, an efficient assignment these sequence sets given, also have large re-use distance. Finally, based on above construction, we construct with zero correlation zone (ZCZ) property reduce interference among multi-path environment. constructed ZCZ applied quasi-synchronous CDMA (QS-CMDA) spread spectrum And same
