Deterministic Blind Signal Detection For Acoustic Vector-Sensor Array

This paper links acoustic vector-sensor array signal detection problem to the parallel factor (PARAFAC) model. Exploiting this link, it derives a deterministic PARAFAC signal detection algorithm whose performance is close to nonblind MMSE method. The proposed PARAFAC signal detection algorithm supports small sample sizes, and works well in array error condition. Finally our proposed algorithm doesn't require DOA (direction of arrival) information, so it has blind and robust characteristics. The simulation results demonstrate its validity.
