MIMO Y channel with imperfect CSI: Impact of training and feedback overhead

Zebardast, Hamideh; Zhou, Xiangyun; Maham, Behrouz


Signal space alignment with network coding (SSA-NC) is a cooperative transmission strategy that, under some conditions such as full channel state information (CSI), provides maximum degrees of freedom (DoF) in two-way relay networks. However, obtaining full CSI for SSA-NC requires a significant amount of training and feedback overhead. This paper focuses on the multiple-input multiple-output (MIMO) Y channel and explicitly considers the required training and feedback at the users and relay. We...[Show more]
