Diffusion Affine Projection M-Estimate Algorithm for Multitask Networks

The estimation performance of multitask diffusion affine projection algorithm (MD-APA) will be affected in impulsive noise environment. To overcome this shortcoming, in this paper, a multitask diffusion affine projection M-estimate (MD-APM) algorithm is derived by using the M-estimate function in the multitask network. Simulation results demonstrate that the proposed MD-APM algorithm shows good estimation performance than MD-APA and MD-APSA under impulsive interference environment.
