摘　　要：近来，一种新的具有耳形零相关窗的序列对被提出。这种序列对在非周期相关函数的中间及两端部分都同时具有零相关窗。在异步CDMA系统中，如果系统的同步误差能够控制在耳形零相关窗范围内，该序列对理论上能够完全消除多径及多址干扰。本文提出了一种新的具有耳形零相关窗的三元序列对的构建方法。Recently, sequence pairs with ear zero correlation windows have been proposed. These sequence pairs can produce zero correlation windows both in the middle part and two terminal parts of their aperiodic correlation functions. In asynchronous CDMA communication systems, these sequence pairs appear to be completely removing inter-symbol interference and multi-user interference if the maximum delay is shorter than the length of the “Ear Windows”. In this paper, a novel method for constructing ternary sequences pairs with ear zero correlation zone is presented.
