摘要：
We present a general technique for analyzing the steady-state tracking performance of the recursive least squares (RLS) algorithm for estimating Rayleigh fading channels in terms of the mean squared identification eror (MSIE) or mean squared deviation (MSD). The technique may,be used with a general-order vector-autoregressive (VAR) model. Numerical results obtained using the technique agree closely with experimental results.
