A non-uniform signal set constellation is used in order to provide shaping gain. An approximately Gaussian distribution of the transmitter output signal is achieved by using equally likely signal points with unequal spacing. In this way it is possible to obtain shaping gain without any additional computational effort. The method is also applicable when bit interleaved coded modulation in conjunction with parallel decoding of the individual bit levels is used.
