  • Abstract
    This paper is devoted to two classical sparse problems in array processing: Channel estimation and DOA estimation. It is shown after some background and some recent results in ℓ0 optimization how this latter can be used, at the same computational cost, in order to obtain improvement in comparison with ℓ1 optimization for sparse estimation.
