A radio receiver is suitable for use in an OFDM wireless communications system, in which it is necessary to identify a timing point at a start of a frame. In order to ensure optimum performance of the receiver in multipath environments, it should be synchronised with the first received multipath component, although one or more of the delayed multipath components may be stronger than the first component. A method of determining the time position of the first received multipath component, determines a correlator function from the received signal, and determines the required timing point from a falling edge in a derivative of the correlator function.
