Abstract
A data communications device and method is provided that apply an LMS (Least Mean Square) channel estimation. A coefficient calculation unit generates a signal that represents at least one channel coefficient that is indicative of a property of the channel such as its finite impulse response. Further, an error calculation unit generates an error signal. Dependent on the error signal, the channel coefficients are updated by performing the LMS algorithm using a step size of two to a negative integer power. This allows for a simple, less complex implementation, and may be applied in a wireless local area network receiver for adjusting filter coefficients.
