Blind Equalization of Cross-QAM Signals
Shafayat Abrar, Ijaz Mansoor Qureshi · IEEE Signal Processing Letters · 2006
This letter presents two new blind equalization algorithms that are specifically designed for cross-QAM signals. Proposed algorithms minimize the dispersion of the equalizer output with respect to single or multiple cross-shaped zero error contour(s). Simulations and analysis demonstrate the good performance of the proposed algorithms
