Abstract :
New binary sequence sets with zero correlation zone (ZCZ) have been constructed on the basis of almost-perfect binary and almost-perfect ternary sequences and mismatched filtering. The obtained sequences have energy efficiency close to 1 when length becomes large and in most of cases length of their ZCZ exceeds the upper bound of binary ZCZ sequences. These sequences can be used in quasi-synchronous code division multiple access (QS-CDMA) and radar systems to reduce multi-channel and multi-path interference.
