Abstract:

A sliding window RLS method based on givens rotation is proposed, which can be used to improve calculative efficiency of the least square adaptive algorithm based on QR decomposition and increase data throughput. This method is suitable for high sampling rate application, and the input data with sliding window form can suit more application environment than traditional Givens algorithm. Simulation results are given to demonstrate the effectiveness of the new method.
