The bitmap is Gray encoded. Symbols are normalized so that the average energy is 1. That - is, normalized with \f$\sqrt{2(M-1)/3}\f$. + is, normalized with \f$\sqrt{2(M-1)/3}\f$. For odd values of \f$k\f$, + a regular rectangular constellation is used. Beside hard demapping, this class can also perform soft demodulation, calculating the log-MAP estimate of the individual bits. To use it
