Spectral Efficiency and Energy Efficiency Optimization via Mode Selection for Spatial Modulation in MIMO Systems

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, […]


Detecting Stress Based on Social Interactions in Social Networks

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 […]
