Abstract

In order to manage interference in Long Term Evolution (LTE) using single-input single-output (SISO) or multiuser multi-input multi-output systems (MIMO), we investigate interference alignment mitigation techniques for LTE systems and provide an analytic extension and new method. Although precoding generally is applied for each subcarrier, we observe that using a precoder in the output of OFDM signal will give no significant performance degradation. We validate the results by developing a MATLAB simulation model in order to evaluate the link-level performance.
