Paper Title:
The FPGA Implementation of NLMS Adaptive Interference Cancellation Algorithm
  Abstract

A adaptive interference cancellation algorithm was proposed in this paper,which was based on NLMS algorithm.The NLMS algorithm was achieved on FPGA chips. This paper described the method of the specific implementation. This method introduces bit-shift in terms of subsection instead of division operation, by which the operation speed of FPGA is improved apparently.By Matlab simulating the functions, and analyzing the PSD curve and the constellation of output signals, the adaptive interference cancellation algorithm system based on NLMS achieved expected effect. The better in-band flatness of the PSD curve and the higher convergence rate on constellation were obtained. Therefore, the NLMS adaptive interference cancellation algorithm is chosen as the design with High Performance-price Ratio.
