Transmitting means (10; 20; 20') for transmitting an output signal, comprising: a first filter structure (14a; 14'a) comprising a first combiner configured to extend a first data signal by a first reference signal in order to obtain a first extended data signal, and comprising a first IIR filter for filtering the first extended data signal in order to obtain a first filtered data signal; a second filter structure (14b; 14'b) comprising a second combiner configured to extend a second data signal by a second reference signal in order to obtain a second extended data signal, and comprising a second IIR filter for filtering the second extended data signal in order to obtain a second filtered data signal; a multiplexer for combining the first and second filtered data signals in order to obtain the output signal based on the filtered data signals (18a, 18b); wherein a system response of the first IIR filter based on the first reference signal corresponds to a system response of the second IIR filter based on the second reference signal wherein the first and second combiners (24a, 24b) are configured to insert the reference signal (26a, 26b) in front of (26a-1, 26b-1) and after (26a-2, 26b-2) a data block of the data signal (16a, 16b), and wherein the IIR filters (28a-b), the multiplexer or a signal former are configured to reject an obtained filtered reference signal (26a-1', 26b-1') based on the reference signal (26a-1, 26b-1) placed in front of so that the output signal comprises the filtered data signals (16a', 16b') and the filtered reference signals (26a-2', 26b-2') inserted after the data block and does not comprise the filtered reference signals (26a-1', 26b-1') inserted in front of the data block. a first filter structure (14a; 14'a) comprising a first combiner configured to extend a first data signal by a first reference signal in order to obtain a first extended data signal, and comprising a first IIR filter for filtering the first extended data signal in order to obtain a first filtered data signal; a second filter structure (14b; 14'b) comprising a second combiner configured to extend a second data signal by a second reference signal in order to obtain a second extended data signal, and comprising a second IIR filter for filtering the second extended data signal in order to obtain a second filtered data signal; a multiplexer for combining the first and second filtered data signals in order to obtain the output signal based on the filtered data signals (18a, 18b); wherein a system response of the first IIR filter based on the first reference signal corresponds to a system response of the second IIR filter based on the second reference signal wherein the first and second combiners (24a, 24b) are configured to insert the reference signal (26a, 26b) in front of (26a-1, 26b-1) and after (26a-2, 26b-2) a data block of the data signal (16a, 16b), and wherein the IIR filters (28a-b), the multiplexer or a signal former are configured to reject an obtained filtered reference signal (26a-1', 26b-1') based on the reference signal (26a-1, 26b-1) placed in front of so that the output signal comprises the filtered data signals (16a', 16b') and the filtered reference signals (26a-2', 26b-2') inserted after the data block and does not comprise the filtered reference signals (26a-1', 26b-1') inserted in front of the data block.
