Abstract

Abstract:

Two novel interference alignment (IA) schemes are proposed for the two-cell MIMO uplink transmission system and their respective achievable degrees of freedom (DoF) are derived. The first scheme is the partial selective IA, which can achieve a higher DoF than the traditional selective IA by exploiting the received signals not involved in the IA. The second scheme is the hybrid IA, which exploits both partial selective IA and partial fixed IA schemes and results in the highest DoF compared to these two candidate IA schemes. Simulation results show that the proposed schemes outperform the existing schemes.
