Abstract

Two new constructions of shift sequence are proposed and the upper bound of the shift distinct sequence sets is computed.The concepts of initial point and initial distance are presented.CBIID selects initial point arbitrarily and multiple distinct shift sequence sets are obtained by designing suitable initial distance.By utilizing interleaving technique one can get multiple shift distinct low-correlation zone or zero-correlation zone(LCZ/ZCZ)sequence sets.The initial point is selected flexibly

so it is the expansion of the existing methods.CBVID

which is based on CBIID

designs shift sequence based on different initial distance in a shift sequence set.It can gain more spread-spectrum sequences for quasi-synchronous code-division multiple-access(QS-CDMA)system compared with previous constructions.Shift distinct LCZ/ZCZ sequence sets are allocated to different cells to reduce interference.
