- Abstract
- In this letter, we propose a transmit antenna selection and unitary precoding strategy for maximum-likelihood (ML) detector in interference-aligned multiple input multiple output (MIMO) networks. The proposed transmit antenna selection for ML receiver is to maximize the minimum among all receivers' minimum distances. In order to achieve further performance enhancement, we also propose an unitary precoding strategy for ML detector associated with the antenna selection. Numerical results show that the proposed scheme provides enhanced performance compared with the conventional algorithms.
