In this paper we consider some linear multi-antenna receivers to combat inter-operator interference in non-coordinated WCDMA networks. Adjacent channel interference creates dead zones where the QoS target cannot be reached. We first characterize the importance of this phenomenon by evaluating the dead zone area and the probability of finding a given number of users in it. We then derive a specific reception scheme from the space-time Wiener receiver in order to get the best trade-off between performance and complexity. As a third step we discuss the importance of adjacent channel interference regarding the propagation environment and handover strategy.
