FPGA-Implementation of Parallel and Sequential Architectures for Adaptive Noise Cancelation

摘要

This paper presents a FPGA-based rapid prototyping of an adaptive noise canceller (ANC) using XUP Virtex-Ⅱ Pro development board and Xilinx System Generator. New parallel and sequential architectures of the ANC are proposed and successfully applied to remove noise from electrocardiogram and speech signals. The pipelined architecture were evaluated and compared to existing high-speed systems using objective measurement tests. By providing comparable filtering performances that of the parallel architectures, the proposed sequential system required fewer material resources.
