Limited hilbert cost function for the blind equalizer

摘要

A blind equalization cost function called the "constrained Hilbert cost function" (CHCF) provides for reliable blind convergence of a two- filter equalizer structure. In particular, the CHCF cost function is designed in such a way that the two filters are constrained to be a Hilbert pair. Advantageously, this technique can be used with any blind equalization algorithms, such as RCA, CMA, and MMA.
