Abstract The array calibration for spreading communication system is discussed in this paper. Based on both PARAFAC and array rotation, an array calibration approach is proposed. This calibration approach is employing auxiliary spreading code signal, PARAFAC analysis and array rotation. Array calibration can be performed without the DOA knowledge of auxiliary signal, which is convenient in practice. Simulation result shows that the calibration approach is feasible and efficient.
