A method and arrangement are proposed for compensating intersymbol interference (ISI) in a multicarrier transmission system. Compensation is based on the generation of an estimate of the ISI tail and subtracting the estimate from the received signal. This is achieved by determining an estimate of the transmitted symbols at the receiver by filtering with a transfer function that approximates the inverse of the channel transfer function for the carrier frequencies used. Estimated of two consecutively transmitted symbols are used to generate a difference symbol. When a string of zeroes is appended to this difference symbol and passed through a filter, a transient results which is equivalent to that generated by the consecutively transmitted symbols passed over the channel. |
