Webent type one using the Least Mean Square (LMS) algorithm, it is extremely robust and simple to implement but it has lim-ited performance. The Recursive Least Squares (RLS) adap-tive algorithm is the other well known algorithm, it is more complex but it can yield a very fast convergence. The square-root form of recursive least squares is based The algorithm only started appearing on public forums between 2002 and 2003. Computation of square roots usually depends upon many division operations, which for floating point numbers are computationally expensive. The fast inverse square generates a good approximation with only one division step.
