Performance evaluation of solar energy predictor for wireless sensors
Résumé
Recently, coprime array has been proposed to es-timate the direction of arrival (DoA) of O(MN) sources usingonly O(M +N) physical sensors. In this paper, we investigate anew method to achieve higher degrees of freedom for the coprimearray under the coexistence of K1 non-circular and K2 circularsources. By exploiting the properties of the signal sources, a newmodel is constructed based on a longer virtual uniform lineararray (ULA). Simulation results show that the proposed methodcan identify more sources once the condition K1 +2K2 < 2MNis satisfied.
