A SINR Improvement Algorithm for D2D Communication Underlaying Cellular Networks

In this paper, we study the interference scenario where multiple Device-to-Device (D2D) pairs and one cellular use share the same spectrum resources, and propose a novel D2D signal-to-interference-plus-noise ratio (SINR) improvement algorithm called DSIA from the perspective of precoding and decoding. Numerical results show that in comparison with the traditional spectrum orthogonal scheme, the DSIA will enable D2D to achieve significant SINR gains.
