A method for optimising the processing of a received OFDM, Orthogonal Frequency Division Multiplexed, signal, the OFDM signal comprising a plurality of symbols in the time direction, each symbol comprising a plurality of sub-carriers in the frequency direction, the method comprising the steps of: a) providing a plurality of techniques for channel estimation and equalization of a received OFDM signal; b) receiving one or more symbols of the OFDM signal; c) selecting one of the plurality of techniques to be used on the received one or more symbols or a further one or more symbols of the OFDM signal by: i) performing channel estimation and equalization on the received one or more symbols for each of the plurality of techniques using at least some of the sub-carriers in the received one or more symbols; ii) deriving a distortion parameter for each sub-carrier for each of the plurality of techniques, the distortion parameter defining a measure of the difference between the actual equalized sub-carrier and the ideal sub-carrier for the particular modulation scheme used; iii) comparing the averaged distortion parameter for the plurality of techniques, averaged over the sub-carriers in the received one or more symbols of the OFDM signal; and characterised by iv) selecting the technique which has the lowest power consumption, as long as the averaged distortion parameter falls within a predetermined acceptable range; d) performing channel estimation and equalization on the received one or more symbols of the OFDM signal; and e) repeating steps b), c) and d). a) providing a plurality of techniques for channel estimation and equalization of a received OFDM signal; b) receiving one or more symbols of the OFDM signal; c) selecting one of the plurality of techniques to be used on the received one or more symbols or a further one or more symbols of the OFDM signal by: i) performing channel estimation and equalization on the received one or more symbols for each of the plurality of techniques using at least some of the sub-carriers in the received one or more symbols; ii) deriving a distortion parameter for each sub-carrier for each of the plurality of techniques, the distortion parameter defining a measure of the difference between the actual equalized sub-carrier and the ideal sub-carrier for the particular modulation scheme used; iii) comparing the averaged distortion parameter for the plurality of techniques, averaged over the sub-carriers in the received one or more symbols of the OFDM signal; and characterised by iv) selecting the technique which has the lowest power consumption, as long as the averaged distortion parameter falls within a predetermined acceptable range; i) performing channel estimation and equalization on the received one or more symbols for each of the plurality of techniques using at least some of the sub-carriers in the received one or more symbols; ii) deriving a distortion parameter for each sub-carrier for each of the plurality of techniques, the distortion parameter defining a measure of the difference between the actual equalized sub-carrier and the ideal sub-carrier for the particular modulation scheme used; iii) comparing the averaged distortion parameter for the plurality of techniques, averaged over the sub-carriers in the received one or more symbols of the OFDM signal; and characterised by iv) selecting the technique which has the lowest power consumption, as long as the averaged distortion parameter falls within a predetermined acceptable range; d) performing channel estimation and equalization on the received one or more symbols of the OFDM signal; and e) repeating steps b), c) and d).
