摘要
The present invention is applicable to the communication field, which provides a blind equalizer and a blind equalization processing method. The equalizer comprises a weight updating unit and a filter, wherein the weight updating unit includes a first weight updating module, a second weight updating module and a weight combination module. In the present invention, a weight vector is updated by minimizing the error term of the first weight updating module and maximizing the logarithm of the local posterior probability density function used by the second weight updating module, and then according to the updated weight vector, the received signal vector is equalized and output, thereby a blind equalizer is realized, which can improve the convergence speed and the steady state performance.
