Asynchronous Interference Mitigation in Cooperative Base Station Systems

Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multi-cell multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems, is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can at best only ensure that the desired signal components
