摘要
This paper presents the convex combination of two DLMS (CC-DLMS) algorithms for the distributed estimation problem over diffusion networks. The proposed algorithm has better performance than conventional DLMS algorithm. Also, the tracking capability is improved. In CC-DLMS algorithm, two DLMS algorithms with different step sizes are combined, which results in faster convergence rate as well as lower final error at the price of an increase in complexity. We demonstrate the good performance of the introduced algorithm thorough several simulation results.
