This paper considers a device-to-device (D2D) communications underlaid multiple-input multiple-output cellular network and studies D2D mode selection from a previously unexamined perspective. Since D2D mode selection affects the network interference profile and vice versa, a joint D2D mode selection and interference management is desired but challenging. In this paper, we propose a holistic approach...
This paper considers a hybrid cochannel MIMO cellular network with both cellular and device-to-device (D2D) users, and studies, from a new perspective, mode selection (cellular or D2D mode) for the potential D2D users joining the network. We propose a new mode selection scheme that takes into account not only the interference caused to the potential D2D users, but also the interference caused by the...
In this paper, we study in depth the alternating minimization algorithm (AMA) proposed by S. W. Peters and R. W. Heath Jr. Among iterative interference alignment (IIA) schemes, AMA is considered more feasible for real applications than other IIA schemes. However, no research has investigated how AMA is affected by some real system characteristics. Motivated by this, we look into the effects when taking...
In this paper, we present a novel scheme that aligns the interference from the antennas of the cognitive user (CU) such that the interference to the primary user (PU) is nullified or minimized. The two-user multiple-input multiple-output (MIMO) interference channel is considered. We assume that the transmission bandwidth of the CU is wider than that of the PU, and the spectrum of the PU is called...
