摘要：
There is provided spectrum shaping of a signal. A frequency-domain representation of the signal to be spectrum-shaped is provided. The signal is associated with a set of constellation points having a minimum distance. A spectrum-shaped signal is determined by altering a proper subset of the constellation points whilst maintaining the minimum distance between all of the constellation points. The spectrum-shaped signal is transformed into a time-domain signal.
