TECHNIQUE FOR IMPROVING THE BLIND CONVERGENCE OF A TWO-FILTER ADAPTIVE EQUALIZER

摘要

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