Abstract:
An analysis of the interference cancellation configuration working based on the least-squares (LS) adaptive algorithms is presented in this paper. The existence of a "residual leakage" phenomenon of the useful signal, to the output of the adaptive filter, through the error signal is demonstrated. As a consequence, the useful signal can be attenuated, up to complete cancellation. This process is important for low values of the weighting parameter $lambda$ and is practically absent for $lambda$ close to unit. The simulations performed in an echo cancellation configuration support the theoretical findings.
