Abstract :
We propose a new blind system identification structure and its cost function. The proposed cost function is of a quadratic form and has a unique solution. In addition, the proposed scheme can employ iterative algorithms which achieve less computational complexity and can be easily realized in real time processing. In order to verify the effectiveness of the proposed schemes, several computer simulations including a 64-QAM signal equalization have been shown
