The present invention provides a method of estimating parameters of a mobile radio channel which are used for providing the equalization and synchronization of the radio channel. The channel is modelled as a discrete number of independent Rayleigh-faded propagation paths. First, the relative delay of each path is estimated, using maximum likelihood methods. Using this information, the associated time-varying path weights are then determined using a least-squares fit. This is sufficient information to estimate the impulse response of the channel. The actual equalizer weights are then obtained by inverting the estimated channel impulse response.
