An Improved Affine Projection Algorithm and Its Application in Echo Cancellation
Based on the variable step-size affine projection algorithm,the idea of multiple forgetting factors and variable projection order is proposed.On the one hand,the accurate estimation of error energy is realized in order to achieve faster convergence rate and lower final misalignment.On the other hand,the reduction of computational complexity can be achieved.The simulation results show that the proposed algorithm achieves significant improvement in the convergence rate,misalignment and computational complexity compared with variable step-size affine projection algorithm,variable projection order affine projection algorithm and variable step-size and rojection order affine projection algorithm without multiple forgetting factors.
