ADAPTIVES FREQUENCY DOMAIN FILTER MIT PARTITIONIERTEN BLÖCKEN |
摘要 |
The partitioned block frequency domain adaptive filter according to the invention includes a plurality of parallel arranged filter partitions. Each filter partition models a part of an impulse response of the adaptive filter and has update unit for updating filter coefficients of that filter partition by a circular convolution. The update unit intermittently constrain these filter coefficients by eliminating circular wrap-around artifacts of the circular convolution. The update unit is arranged for updating the filter coefficients in dependence on at least part of the circular wrap-around artifacts, resulting in an improved convergence behavior of the adaptive filter. |
