가중치 함수 기반 적응적 조합 계수를 갖는 Diffusion LMS 알고리즘
박종훈(JongHun Park),전재현(JaeHyun Jeon),남상원(Sang Won Nam) 대한전자공학회 2017 대한전자공학회 학술대회 Vol.2017 No.6
In this paper, we propose a new combination of diffusion LMS coefficients, whereby combination coefficients control the amount of obtained information from each node. Specifically, the adaptive combination coefficients obtained by using a decreasing and positive weighting function are utilized to improve better convergence. In various noisy environments, the weighting function assigns more proper values, proportional to SNR of nodes, to combination coefficients. The computer simulation results show that the proposed algorithm yields better performance rather than other algorithms for system identification.
