Int. Sig. Proc. Workshop on Higher Order Statistics, Chamrouse, France, July 1991.

, 2007
Direction finding techniques are usually based on the 2ndorder statistics of the received data. In this paper, we propose a MUSIC-like direction finding algorithm which uses a matrix-valued statistic based on the contraction of the 4thorder cumulant ...
