... per- formance in estimating {s k−δ }, there exists a blind equalizer in its immediate neighborhood. Using the converged blind equalizer w δ as an estimate of the MMSE equalizer results in the following ... known training sequences to adaptively extract channel information. The main drawback with this approach is bandwidth consuming due to training. To overcome this resource wastin...

Based on their algorithm, the blind equalizer achieves ... for colored input due to its inadequate constraint. In this section, we will see that our proposed blind equalizer converges to trained MMSE equal- izer for high SNR systems...
