Semi-Blind Signal Extraction for Communication Signals by Combining Independent Component Analysis and Spatial Constraints

Semi-Blind Signal Extraction for Communication Signals by Combining Independent Component Analysis and Spatial Constraints

Signal of interest (SOI) extraction is a vital issue in communication signal processing. In this paper, we propose two novel iterative algorithms for extracting SOIs from instantaneous mixtures, which explores the spatial constraint corresponding to the Directions of Arrival (DOAs) of the SOIs as a...
