In this thesis, strategies & implementation of high speed fpga implementation of the lms filter based on the lms algorithm is described. the least mean square algorithm was found to be the most efficient training algorithm for fpga based adaptive filters. We have implemented our project using an adaptive filter based on the fast lms algorithm and interfaced the fpga with hardware peripherals, a microphone and a speaker, to capture the noise and play the reduced noise result respectively. The lms filter was processed and implemented to the fpga board since it is supported by hdl. experimental results show that the proposed hardware implementation method has a high degree of noise cancellation performance. This project presents the adaptive noise cancellation filter using rls algorithm suitable for noise cancellation and the results are verified by plotting the output using matlab.
