Abstract :
A new decorrelation algorithm through perpendicular translation based on Uniform Circular Array (UCA) has been proposed in this paper. More than one covariance matrices were generated by shifting the array of received signal at two perpendicular directions firstly, and then a new covariance matrix which was a full rank matrix was obtained by averaging the previous matrixes and the signals mentioned before were converted to independence. The simulation results showed that this method was feasible.
