Downlink Interference Alignment With Nuclear Norm and Zero Forcing
This paper proposes the new approach for the interference alignment downlink scheme. This approach is our manner to explore the feasibility of linear interference alignment (IA) in MIMO cellular networks. The principle is to align and remove the interference of the neighboring base stations (BS) which belong to the others cells (inter-cell interference) using precoder of the transmitter and decoder from the receive but also remove the interference user from the same cell. We use an optimization with nuclear norm in the both cases. Our simulations show the better results than the orthogonalized MinLeak.
