Abstract

A transmission system and a transmitter (T) for such a system are disclosed for transmitting a digital signal (sr), encoded in symbols (Si), from the transmitter (T) to a receiver (R) at an arbitrary frequency position by quadrature modulation. In the transmitter, one of the two quadrature components (ki, kq) is delayed before the quadrature modulation by a given time interval (td).
