Construction and Application of OVSF-ZCZ Originated from LS and GO Sequences

Abstract

ZCZ sequences have been confirmed with the capability in interference mitigation in multipath fading channel. On the other hand, OVSF has been successfully applied in WCDMA for separating different channels with different transmission capacity. In this paper, novel OVSF-ZCZ sequences originated from LS and GO sequences have been proposed for CDMA systems with different service requirements. The construction method is discussed and the performance of the system is evaluated.
