Abstract

The basic idea of the invention is to define the possible error positions in two erroneously received data frames. This information is used together with the error-free information included in the erroneous frames to regenerate the sent frame. The error positions are defined by comparing the erroneous data frames. Having defined the error positions, a candidate for the sent frame is generated by replacing the symbols in the error positions by a possible symbol combination. The generated frame is checked for errors, and if found to be error free, the generated frame is accepted. If the frame is erroneous, another possible symbol combination in the error positions is tried. If the correct frame can not be found by trying all the possible symbol combinations in the estimated error positions, a new retransmission is requested.
