abstract = {We consider the blind identification of FIR channels
 with a single input and multiple outputs when the input signal
 is sparse. The problem is equivalent to identifying the mixing
 matrix for underdetermined blind source separation, but with
 temporal correlation among the sources. The length of each
 channel is assumed known, or previously estimated. Exploiting
 the sparse character of the input signal, the algorithm solves
 sequentially the three identification problems: estimating the
 directions of each column of the channel matrix; estimating their
 L₂-norm; and finding the most likely order of the columns. The
 performance of the algorithm in additive noise and its computational
 cost are compared against subspace-based techniques.},
