An exponentiated gradient adaptive algorithm for blind identification of sparse SIMO systems |

---|---|---|
Sparse impulse responses are encountered in many acoustic and wireless channels. Recently, a class of exponentiated gradient (EG) algorithms has been proposed. One of the algorithms be- longing to this class, the so-called EG algorithm, converges and tracks much better than the classical stochastic gradient, or LMS, algorithm for sparse impulse responses. In this paper, we apply this technique to blind identification of a sparse SIMO system and develop the multichannel EG algorithm. A simple experi- ment demonstrates its advantage in convergence compared to the MCLMS algorithm. |
