| Abstract(in English) | In this paper, we propose a pipelined architecture for the normalized least mean square(NLMS) adaptive digital filter(ADF). The hardware implementation of the NLMS however has not been proposed yet, and the proposed architecture is the first attempt to implement the NLMS ADF in the pipelined fashion. The architecture is based on an equivalent expression of the NLMS which is derived in this paper. It is shown that the proposed architecture achieves a constant and a short critical path without producing the output latency. Besides, it maintains the advantage of the NLMS that the step size which assure the convergence is determined automatically. We provide the results of computer simulations of system identification to verify that the proposed architecture achieves the identical convergence characteristics as that of the NLMS. |
