摘要：
We discuss possible approaches for the adaption of the step width of Step-Adaptive Approximate Least Squares. We present and compare two low complexity and practically feasible adaptation functions whose parameters have been optimized based on computer simulations. We show that by applying these approaches the performance deviation of Step-Adaptive Approximate Least Squares lies within the single percentage range compared to the optimal least squares solution.
