Abstract :
In this paper, we are concerned by the self-calibration of a linear equispaced array impinged by correlated sources. We propose a new method based on the fact that sources have discrete distribution which is meaningful in a digital communication context. The assumption of discrete sources allows an estimation, in the LS sense, of the mixing matrix which is then used to compute the sensor gain, phase and location errors.
