Abstract

In this paper, we present a set of sequence pairs which produce zero correlation windows not only in the middle part of the sum of aperiodic correlation functions, but also in the two terminal parts. We name it "Ear Windows". In asynchronous CDMA communication system, this set of sequences appears to be completely removing the intersymbol interference (ISI) and multiuser interference (MUI) caused by the multipath effect if the maximum delay is shorter than the length of the "Ear Windows". We can also find application in M-ary modulation. The intercode interference will be mitigated drastically.
