A method of determining a signal quality parameter in a radio communications device includes: measuring a signal error parameter of a received signal (); comparing said measured signal error parameter to a threshold level (), and determining the signal quality parameter on the basis of a reference signal error parameter value () in the event that the measured signal error parameter value is less than the threshold level ().

Measuring received signal quality

The present invention provides an equalizer () and a method for computing equalizer filter coefficients in a communication receiver. The equalizer filter coefficients are computed on the basis of a real matrix T which is generated from channel estimation vector f, which is derived from the channel estimation inputs.
