A descriptive of an adaptive noise canceler using Widrows LMS algorithm is presented. A computer simulation of canceler performance adaptive convergence time and frequency transfer function was written for use as a design tool. The simulations, assumptions, and input parameters are described in detail. The simulation is used in a design example to predict the performance of an adaptive noise canceler in the simultaneous presence of both strong and weak narrow-band signals a cosited frequency hopping radio scenario. On the basis of the simulation results, it is concluded that the simulation is suitable for use as an adaptive noise canceler design tool i.e., it can be used to evaluate the effect of design parameter changes on canceler performance.
