摘要

在几乎完美二值序列和几乎完美三值序列的基础上，利用不匹配滤波构造了新的零相关带二值序列集。所得序列在长度较大时能量效率接近1，且大部分序列的ZCZ长度超过二进制ZCZ序列的上界。这些序列可用于准同步码分多址(QS-CDMA)和雷达系统中，以减少多信道和多径干扰。

New Binary ZCZ Sequence Sets with Mismatched Filtering

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.
