Adaptive Filter Definition An adaptive filter is a time-variant filter whose coefficients are adjusted in a way to optimize a cost function or to satisfy some predetermined optimization criterion. Linear adaptive filters . There are different approaches used in adaptive filtering… The overall system operates on a single sampling rate fs, thus the adaptive ﬁlters are fullband ﬁlters, as illustrated in Figure1. 10. 7. 0000004050 00000 n

The kernel adaptive filtering (KAF) algorithms are a family of nonlinear adaptive filtering algorithms developed in kernel (or feature) space [12], by using the linear structure and inner product of this space to implement the well-established linear adaptive filtering algorithms (e.g., LMS, RLS, etc.) Adaptive Filtering 2 • For a number of applications, adaptive IIR filters may have a compuatational and modelling advantage. startxref
