Abstract
The present invention relates to a method and apparatus for adaptive channel estimation for signal-amplitude-based communications systems. In one arrangement, the method comprises: receiving an observation (r) of a transmitted coded symbol (d); generating, with a weight generator, a first coefficient (v) for weighting the received observation based on an estimate of the transmitted coded symbol (d_est), the first coefficient having a magnitude that is invariable with the amplitude of the transmitted coded symbol; and forming a new channel estimate (h_est) based on a weighted observation using the first coefficient (v).
