Survey of Blind Equalization Algorithms

Blind equalization has been attracting much attention in the field of communication signal processing, which can implement the channel equalization on the basis of received signal sequence without training sequence. Blind equalization technique can effectively overcome inter-symbol interference, and play a significant role in improving the quality of communication. The recently developed blind equalization algorithms are extensively reviewed, which include the artificial intelligence algorithm, signal detection algorithm, particle filter algorithm, wavelet transform algorithm, matrix decomposition algorithm and unified model algorithm. Performance analysis about the leading blind equalization algorithms is given, and open issues on blind equalization are also pointed out.
