Abstract
To overcome the defects of multi-path underwater acoustic channel and Constant Modulus Algorithm (CMA), time diversity blind equalization algorithm based on orthogonal wavelet transform (WT-CTDE) was proposed. In this proposed algorithm, time diversity technique is applied to hyperbolic tangent error function blind equalizer based on constant modulus algorithm (HCMA) and combined with Decision Directed (DD) algorithm and Phase Lock Loop(PLL), and orthogonal wavelet transformation is employed for a transformation to input signals. The proposed WT-CTDE algorithm can not only overcome phase rotation and multi-path propagation but also get small Mean Square Error (MSE) and fast convergence rate. Its performance was proved by the simulations in underwater acoustic channels.
