摘要

The use of an iterative method for equalization of acoustic systems, the channel estimates of which are obtained from supervised system identification (SSI), is investigated. An optimally-stopped weighted conjugate gradient (OS-WCG) algorithm is presented. In the presence of system identification errors (SIEs), a peak of weighted direct-to-reverberant ratio (WDRR) in the iterative process is shown. Then a method to estimate the iteration index of the peak is provided. Finally, a stopping condition for the iteration is proposed. Evaluation results show that using OS-WCG, an improvement up to 20 dB in C₅₀ and 0.141 s in T₃₀ can be achieved.
