The authors have presented a novel dirty paper coding scheme which followed Costa's paper analytically and allowed the recoverability of the dirt. Their scheme implemented random binning in a systematic manner using a trellis and used Viterbi algorithm to quickly obtain a PIP-TCM codeword that is almost orthogonal to the realization of the dirt. They empirically demonstrated that this scheme performs close to an equivalent TCM code on AWGN channel. They also showed that coding gain increases as design spectral efficiency and number of states are increased.
