A new algorithm for fast blind equalization of wireless communication channels

Tong et al. (see IEEE Trans. on Information Theory, March 1994) has proposed a parametric approach for blind equalization based solely on the second-order statistics. It first demonstrates the possibility of achieving satisfactory blind equalization by using a few hundred data samples in some typical wireless communication scenarios. Nevertheless, the algorithm is still far from optimal and is quite computationally intensive. In this paper, we use a different approach and derive a new algorithm which is less complicated as the original one. Simulation studies also show that some improvement of the new approach over its alternative in some scenarios
