Degrees of Freedom on the K-User MIMO Interference Channel with Constant Channel Coefficients for Downlink Communications

Abstract

In this paper, we study degrees of freedom for the K-User multiple-input multiple-output (MIMO)-interference channel (IFC) with constant channel coefficients. In this channel, we investigate how many total number of transmit antennas, M1 + M2 + . . . + MK , are required in minimum to achieve di = 1, ∀i degrees of freedom when all receivers have N = 2… (More)
