Interference-Aware Receiver Structure for Multiuser MIMO and LTE

In this paper, the authors propose a novel low-complexity interference-aware receiver structure for multi-user MIMO that is based on the exploitation of the structure of residual interference. They show that multi-user MIMO can deliver its promised gains in modern wireless systems in spite of the limited Channel State Information at the Transmitter (CSIT) only if users resort to intelligent interference-aware detection rather than the conventional single-user detection. As an example, they focus on the Long-Term Evolution (LTE) system and look at the two important characteristics of the LTE pre-coders, i.e., their low resolution and their applying Equal Gain Transmission (EGT).
