Abstract

An overview is given of recent advances in constant envelope combined coding and modulation. Modulation codes and trellises are discussed, and major classes of trellis modulation codes are described. Continuous phase modulation is defined, and concatenations of phase codes and convolutional codes are examined. The ultimate capability of phase modulation coding and the size of CPM trellis codes are addressed. Implementation issues are considered
