A device and method for estimating multipath jointly sparse channels. The method comprises receiving a number K of signal components by a number P of receiving antennas, where P>=2. The method further comprises estimating the sparsity condition of the multipath jointly sparse channels. The method further comprises, if the sparsity condition is not satisfied, estimating the channels by using a non-sparse technique. The method further comprises, if the sparsity condition is satisfied, estimating the channels by using a sparse technique.
