【Abstract】 The blind equalization technology can reduce Intersymbol Interference(ISI),compensate the channel′s characteristic and renew transmitting signals accurately,so it becomes the key technique in the wireless communication system.The step-size of Godard algorithm can affect the convergence result.In this paper,a new Godard blind equalization algorithm based on the fuzzy neural network(FNN) controlling step-size is proposed,and it using the control functions to improve the control precision of step-size.The capability of the new algorithm is proved by computer simulation.更多还原
