Abstract :
The 2r th mean convergence of an adaptive filtering algorithm C_{n+ 1} = C_{n} - a_{n}(C_{n}^{T} X_{n} - \\alpha _{n}) X_{n} is studied, where \\alpha _{n} \´s and X_{n} \´s are useful random signals and observation vectors, respectively, and { a_{n} } is a sequence of positive numbers decreasing to zero. In this work, we suppose that the sequence {(\\alpha _{n},X_{n})} is a stationary mixing sequence ( \\rho -mixing, \\phi -mixing, or \\psi -mixing). Under some additional conditions it is shown that C_{n} converges to c_{\\ast } in the 2r th mean, where c_{\\ast } is the unique solution of the Wiener-Hopf equation.
