Abstract :
This paper presents a sequential architecture of a pipelined LMS-based adaptive noise cancellation to remove the power-line interference (50/60 Hz) from electrocardiogram (ECG). This architecture is implemented on on FPGA using XUP Virtex-II Pro development board and Xilinx system generator (XSG). The proposed architecture was evaluated using real ECG signals from the MIT-BIH database. Hardware requirement of this adaptive noise canceller is presented for various filter lengths.
