QUADRILINEAR DECOMPOSITION-BASED BLIND SIGNAL DETECTION FOR POLARIZATION SENSITIVE UNIFORM SQUARE ARRAY
Ying Shi, Xiaofei Zhang · Electromagnetic waves · 2008
This paper links the polarization-sensitive-array signal detection problem to quadrilinear decomposition model.Exploiting this link, it generates a deterministic blind quadrilinear decompositionbased signal detection algorithm, which doesn't require DOA (direction of arrival) and polarization information and has blind and robust characteristics.The proposed algorithm fully utilizes the polarization, spatial and temporal diversity.The simulation results reveal that the performance of blind quadrilinear decomposition-based signal detection algorithm for polarization sensitive uniform square array is close to nonblind MMSE method, and even works better than trilinear decomposition algorithm.
