Interference alignment for multi-user MIMO interference channels via a Riemannian optimization approach


Interference alignment (IA) is a technique shown to be able to achieve a significant overall throughput in a μ - user multiple-input multiple-output (MIMO) interference channel (IC). In this paper, we try to modify the conventional IA designs to achieve enhanced sum-rate performance. We jointly design transmit and receive IA filters (precoding and… (More)
