20 Claims

1. An adaptive filter circuit comprising:

a plurality of filter cores associated with each other and configured to perform a calculation operation on a first target input signal; and

an auxiliary core configured to:

generate cross-terms between block correlation matrices respectively corresponding to kernels that correspond to the first target input signal; and

provide the cross-terms to the plurality of filter cores,

wherein the plurality of filter cores are further configured to estimate effective channels respectively corresponding to the kernels based on the cross-terms.
