Novel DFE for Underwater Acoustic Channels

摘要：

　　In underwater acoustic communication systems,the channel equalization community has recently given much attention to decision feedback equalization (DFE).It is because that the DFE offers intersymbol interference (ISI) cancellation with reduced noise enhancement.However,its key algorithm such as constant modulus algorithm (CMA) has moderate convergence rate and steady-state mean square error (MSE),which is not sufficient for the receive system of communication.So a new cost function is defined and then a novel DFE based on such cost function is proposed.The efficiency of the proposed DFE is proved by computer simulations.
