An Efficient DoF Scheduling Algorithm for Multi-Hop MIMO Networks

Degree-of-Freedom (DoF)-based model is a simple yet powerful tool to analyze MIMO's Spatial Multiplexing (SM) and Interference Cancellation (IC) capabilities in a multi-hop network. Recently, a new DoF model was proposed and was shown to achieve the same rate region as the matrix-based model (under SM and IC). The essence of this new DoF model is a novel node ordering concept, which eliminates potential duplication of DoF allocation for IC. In this paper, the authors investigate DoF scheduling for a multi-hop MIMO network based on this new DoF model.
