Abstract:- This paper deals with simulation of a Serial Least Mean Square (SLMS) adaptive filter algorithm for echo cancellation of speech-band data transmission with higher computational speed. A regular dial-up telephone network has been chosen for this application. Unlike the other conventional algorithms, SLMS algorithm is reliable, simple and has better convergence characteristics. An adaptation constant is suitably chosen for the analysis to reduce the number of iterations thus achieving much higher speed while maintaining a very high accuracy level. The simulation results are also presented which meets the desired output. The core has been designed using VERILOG as the HDL language and synthesized with FPGA logic unit which targets FPGA SPARTAN S05VQ100 at frequency of 50 MHz
