Abstract :
The diffusion least mean p-power (LMP) algorithm is extended with adaptive variable power p in the generalised Gaussian distribution (GGD) environments. The GGD is one of the widely used distributions in the signal processing area. For the proposed method, priori knowledge of the distribution parameters is not required. Furthermore, it is robust to the preselected initial power order. Numerical results are provided to verify the performance of the proposed method.
