Abstract

A method for generating a symbol mapping table (14) in a memory (13) comprises: selecting an initial set of pulse train segments having a time-granularity corresponding to a second oversampling clock rate (F2), determining a complex energy coefficient of the pulse train segments of the initial set at the carrier frequency, selecting a subset of the pulse train segments of which the complex energy coefficients at the carrier frequency closely approximate the quantified complex output states of the modulation device, so that each quantified complex output state is uniquely mapped to a pulse train segment of the subset, for each pulse train segment mapped to a quantified complex output state, recording at a memory address associated to the quantified complex output state a quantified symbol (16) encoding the pulse train segment.
