Incorporating cloud computing into heterogeneous networks, the heterogeneous cloud radio access network (H-CRAN) has been proposed as a promising paradigm to enhance both spectral and energy efficiencies. Developing interference suppression strategies is critical for suppressing the inter-tier interference between remote radio heads (RRHs) and a macro base station (MBS) in H-CRANs. In this paper,...
This paper introduce the theory of the adaptive noise canceling system and LMS algorithm, also present the emulational chart of adaptive filter based on LMS algorithm. Analysis of the emulational result indicate the adaptive noise canceling technic can effectively cancel interferential sine wave, so in the disposal of sound signal can eliminate background noise and achieve the purpose of advancing...
An improvement adaptive LMS algorithm is introduced, the theoretical analysis and computer simulation of this algorithm are provided for confirmation that it resolved the contradiction between convergence rate and static error contradiction in the tradition LMS algorithm, and applied this algorithm in the disturbance cancellation system. It was concluded that this algorithm has the merits such as...
