Abstract--This paper introduces a new mutual coupling com-
pensation method based on the minimum norm solution to an un-
derdetermined system of equations. The crucial advantage over
previous techniques is that the formulation is valid independent
of the type of antenna element and provides good results in situa-
tions where signal strengths vary considerably. In using the matrix
pencil algorithm to estimate the directions of arrival, the examples
show that the proposed method results in significantly lower bias
than the traditional open circuit method. The analysis of mutual
coupling is also applied in the context of a Code Division Multiple
Access communication system.
Index Terms--Code division multiaccess, direction of arrival es-
timation, matrix pencil, MUSIC, mutual coupling compensation.
