Title:
適応フィルタ及び適応フィルタの動作方法
Document Type and Number:
Japanese Patent JP6928496
Kind Code:
B2
Abstract:
The present application relates to an adaptive filter using resource sharing and a method of operating the adaptive filter. The filter comprises at least one computational block, a monitoring block and an offset calculation block. The computational block is configured for adjusting a filter coefficient, c i (n), in an iterative procedure according to an adaptive convergence algorithm. The monitoring block is configured for monitoring the development of the determined filter coefficient, c i (n), during the performing of the iterative procedure. The offset calculation block is configured for determining an offset, Off i , based on a monitored change of the filter coefficient, c i (n), each first time period, T 1 , and for outputting the determined offset, Off i , to the computational block if the determined filter coefficient, c i (n), has not reached the steady state. The computational block is configured to accept the determined offset, Off i , and to inject the determined offset, Off i , into the iterative procedure.
