摘要：
In this paper, we propose a mutual interference steering (IA) method for interference elimination in co-existing Phased Array (PA) radar and multi-user MIMO communication systems, namely, radar-communication systems. Although ergodic interference alignment (IA) method have been proposed to cancel the mutual interferences, it will definitely reduce the degrees-of-freedom (DoFs) of communication systems. Differently, our proposed mutual IA method allows to improve the DoFs of communication system without sacrificing the radar performance. It is examined by the Neyman-Pearson (NP) test for radar functionality, while the communication performance is evaluated by DoFs and bit error rate (BER) analysis. Both theory analysis and numerical results are provided to validate the effectiveness of the proposed IA method for co-existing radar and communication systems.
