Optimization of LMS Algorithm for System Identification

Key Words: Adaptive Digital Filters, LMS algorithm, SNR, MSE 1. INTRODUCTION The usual method of estimating a signal corrupted by additive noise is to pass it through a filter that tends to suppress the noise while leaving the signal relatively unchanged [1]. Filters used for the above purpose can be fixed or adaptive. The design of fixed filters is based on prior knowledge of both the signal

Analysis and Simulation of Adaptive Filter with LMS Algorithm

Some adaptive filter applications, such as adaptive echo cancellation and adaptive noise cancellation, require adaptive filters with a large filter length. If you apply the standard LMS algorithm to the adaptive filter, this algorithm might take a long time to complete the filtering and coefficients updating process. This length of time might cause problems in these applications because the
