Abstract

The performance of blind equalization algorithm is closely related to the characteristics of the channel. Eigenvalue spread of the channel can reflect the influence of the channel on the input signal. The paper presents a method to distinguish eigenvalue spread of the wireless channel by the correlation coefficient of the input vector. For channels with different eigenvalue spread, based on the consideration of the complexity and the performance, different blind equalization algorithms are chosen. At the same time a decorrelation blind equalization algorithm is proposed. Simulations verify the effectiveness of the proposed algorithms.
