Variable Momentum Factor Odd Symmetry Error Function Blind Equalization Algorithm

By the analysis of Odd symmetry error Function blind equalization Algorithm based Decision Feedback Equalizer (OFA-DFE), Variable Momentum Factor Momentum Odd symmetry error Function blind equalization Algorithm based Decision Feedback Equalizer(VMFMOFA-DFE)is proposed. The proposed algorithm uses error function with characteristics of odd symmetry to reduce mean square error, in order to further improve the performance of the algorithm using variable factors to control the momentum term and introducing variable momentum factor to decision feedback equalizer to adjust farword equalizer of decision feedback. Simulation tests with underwater acoustic channel indicate that the proposed algorithm has not only faster convergence rate but also less mean square error.
