ABSTRACT:
A hierarchical adaptive equalizer and a design method thereof are disclosed. The design method divides N delay elements into a plurality of adaptive algorithms, each of the adaptive algorithms having β delay elements. The design method logically structures a hierarchical tree with the adaptive algorithms. The hierarchical tree comprises α levels. A top first level of the hierarchical tree comprises βα−1adaptive algorithms. A top second level of the hierarchical tree comprises βα−2adaptive algorithms. A bottom level of the hierarchical tree comprises an adaptive algorithm.
