Successive Interference Mitigation in Multiuser MIMO Channels

Abstract— Successive Interference Mitigation in Multiuser MIMO Channels. Motivated by the work of Dahrouj and Yu in applying the Han-Kobayashi transmission strategy for mitigating the intercell interference in a multi-cell multi-user multiple-input single-output Interference network MISO IN, < Final Year Projects 2016 > this paper considers splitting messages into private and common parts in a multi-cell multi-user multiple-input multiple-output interference network (MIMO IN. Specifically, the covariances of the private messages and common messages are designed to optimize either the sum rate or the minimal rate. The common messages and private messages are decoded in sequence using successive decoding. This paper shows how these difficult optimization problems can be adequately solved by means of d.c (d ifference of concave functions) optimization over a simple convex set.
