Achievable Degrees of Freedom Region of the MIMO Relay Networks using the Detour Schemes

Ahmed A. Zewail, M. Nafie, Y. Mohasseb +1

In this paper, we study the degrees of freedom (DoF) of the MIMO relay networks. We start with a general Y channel, where each user has antennas and aims to exchange messages…
