Practical MATLAB Implementation of the Least Mean Squares (LMS) Algorithm with Code Examples
Fundamental Concept of the LMS Algorithm
When avoiding the use of correlation matrices associated with estimating input signal vectors to accelerate LMS algorithm convergence, variable step-size methods can shorten the adaptive convergence process. A primary approach is the Normalized LMS (NLMS) algorithm. The variable step-size update formula can be expressed as W(n+1) = w(n) + e(n)x(n) = w(n) + [step_size], where [step_size] = e(n)x(n) represents the adjustment term for iterative filter weight vector updates. To achieve rapid convergence, appropriate selection of the variable step-size is essential. One potential strategy involves minimizing the instantaneous squared error as much as possible, using it as a simplified estimate of the Mean Squared Error (MSE), which constitutes the foundational principle of the LMS algorithm.
