Fuzzy Neural Network Blind Equalization Algorithm Based on Signal Transformation
To recover QAM signals at the receiver of blind equalizer,a Fuzzy C-means clustering Neural Network Blind Equalization Algorithm based on Signal Transformation (ST-FNN-BEA) is proposed.The proposed algorithm uses signal transformation method to debase the computational complexity of equalizer input signals and speed up the convergence rate,and makes use of fuzzy c-means clustering algorithm dividing the equalizer input signals into each cluster center with different membership values to improve the equalization performance.The proposed ST-FNN-BEA outperforms Neural Network Blind Equalization Algorithm (NN-BEA) and Neural Network Blind Equalization Algorithm based on Signal Transformation (ST-NN-BEA) in improving convergence rates and reducing mean square error.The performance of ST-FNN-BEA is proved by the computer simulation with underwater acoustic channels.
