To eliminate the multiple access interference, approximately synchronised code division
multiple access systems employ spreading sequence sets with low or zero correlation zone …

Active sensing is a growing research field with long-standing open problems, whose
applications range from CDMA communication systems, ultrasonic imaging or ranging …

In synchronous CDMA system, the orthogonal spreading sequences are employed to
reduce the multiple access interference. However, as the frequency selectivity of the …

By interleaving one length-N perfect sequence or ideal sequence according to elaborate
phases, a new method of construction of zero correlation zone (ZCZ) and low correlation …

5G physical random access channel (PRACH) will use new preamble formats based on
short Zadoff-Chu (ZC) sequences to enable new use cases. These formats result however in …

For various quasisynchronous (QS) CDMA systems such as LAS-CDMA system which
emerged recently, in order to reduce or eliminate the multiple access interference and …

In this correspondence, we present new construction methods for quaternary low-correlation
zone (LCZ) sequence sets from a binary sequence with good autocorrelation. We show that …

In this paper, given a composite integer n, we propose a method of constructing quaternary
low correlation zone (LCZ) sequences of period 2/sup n/-1 from binary sequences of the …

Sequence families with zero or low correlation zone can be used in the quasi-synchronous
code-division multiple-access (QS-CDMA) communication systems. Interleaving techniques …

To eliminate co-channel and multipath interference, a spreading sequence set with a low or
zero correlation zone can be used in an AS-CDMA system. Here, lower bounds on aperiodic …
