A BALANCED PRECODING SCHEME FOR THE TWO-USER SISO X CHANNEL WITH OPTIMAL DOF AND A SMALL POWER OFFSET
Abstract
In this paper we propose a structured low-latency interference alignment scheme for the two-user single-input single-output (SISO) time-invariant X channel. The scheme is based on asymmetric (non-circular) complex signals generated by linear precoders and linear zero-forcing receivers. In addition to achieving the optimal (sum) degrees of freedom (DoF) of 4/3, the precoders are balanced in the sense that for pairs of symbols the signal-to-noise …
