Spectral Efficiency and Energy Efficiency Optimization via Mode Selection for Spatial Modulation in MIMO Systems Abstract: In this paper, we consider the multiple-input-multiple-output (MIMO) system employing spatial modulation (SM)-based transmission in Rayleigh fading channels with known slow-varying large-scale fading loss and channel correlations. Observing that the system performance is affected by transmission mechanisms and configurations, […]

Nearest Keyword Set Search in Multi-Dimensional Datasets Abstract Keyword-based search in text-rich multi-dimensional datasets facilitates many novel applications and tools. In this paper, we consider objects that are tagged with keywords and are embedded in a vector space. For these datasets, we study queries that ask for the tightest groups of points satisfying a givenset of keywords. We propose a novel method […]
