摘要：

This paper proposes a multi-cell blind interference alignment (BIA) scheme to eliminate the cross-link interference in the dynamic time division duplex (TDD) wireless communication system. The proposed BIA scheme focuses on the interference between base stations. In the proposed BIA scheme, the transmitter does not need to know channel state information (CSI), and the implementation process is divided into two parts. In the first part, the interfering base station and the users of the interfered cell transmit signal vectors at the same time. In the second part, only the interfering base station transmits signal vectors, which is received by the interfered base station and is employed to eliminate the interference caused in the first part. The proposed scheme can eliminate interference efficiently and achieve a high degree of freedom (DoF).
