Hierarchical QAM a spectrally efficient dc-free modulation scheme.

Hierarchical QAM a spectrally efficient dc-free modulation scheme.

A new spectrally efficient, dc-free modulation scheme called hierarchical quadrature amplitude modulation is proposed. The use of HQAM in high-data-rate digital communication systems opens new possibilities for the practical realization of highly integrated receivers.
