An algorithm to improve the convergence performance of the improved μ-law PNLMS algorithm (IMPNLMS) for non-sparse impulse responses is proposed in this chapter. In this algorithm, an adaptive parameter μ of the μ-law compression for sparse impulse response is incorporated into the IMPNLMS algorithm. Compared with IMPNLMS algorithm, simulation results demonstrate that the proposed algorithm has better convergence performance.
