Method for eliminating interference in an ofdm radio receiver

The invention relates to a method for eliminating interference in an OFDM (Orthogonal Frequency Division Multiplexing) radio receiver In the method, coded signals that are transmitted on subcarriers are received, reliability information generated for the signals being used in their soft decoding In accordance with the invention, the signal-to-interference ration of the subcarrier is used as the reliability information, the signal-to-interference ratio being defined by dividing the amplitude of the received signal by the interference amplitude. The interference amplitude is generated by calculating the deviation of the amplitudes of a set of selected signals from the average amplitude level of the set of signals. The average amplitude level of the set of signals is the mean value, median or some other statistical quantity indicative of the average level of the amplitudes of the set of signals. The deviation from the average amplitude level of the set of signals is the standard deviation, variance or some other statistical deviation-indicating quality of the set of signals. The amplitudes of the set of signals are selected from successive symbols in the time domain and/or from adjacent subcarriers in the frequency domain. The invention also relates to an OFDM radio receiver using the method.
