ABSTRACT:
The invention relates to a data transfer method and a data transfer system between a first and a second transceiver, the data transfer comprising transmitting a data signal from the first transceiver to the second transceiver in a broadband channel, measuring, at the second transceiver, the frequency response of the channel and the frequency response of the data signal from the received signal. Measurement results are compared with each other and a need for change in the frequency response of the data signal is determined on the basis of the comparison. Information about the need for change is transmitted to the first transceiver and the frequency response of the data signal to be transmitted is modified at the first transceiver on the basis of the information.
