Abstract

In wireless communications, blind equalization plays an important role in combating inter-symbol interference (ISI) introduced by multipath fading wireless channels, and its main performance criterions are residual mean square error (MSE), convergence speed, and complexity. In this paper, an efficient blind decision feedback equalization algorithm suitable for wireless communication channels is proposed. The performance of the new method is compared to traditional blind decision feedback algorithm by means of computer simulations, and the simulation results confirm the validity of the proposed method.
