Abstract :
By employing the correlation of the multirate filterbank precoded signals, new methods are proposed for blind channel identification/equalization, blind direct equalization and blind synchronization. Both batch and adaptive algorithms are developed utilizing the correlation cancelling techniques. The new algorithms have broader applications than many existing ones. Their computational complexity is lower and can even be O(N). Simulations demonstrate their good performance
