Optimal Multi-H Phase Codes for Partial Response Continuous Phase Modulation
Rongqiang Mao, John P. Fonseka · 2005
Multi-h partial response CPM signals are analyzed at pre-selected number of states in contrast to the standard method of analyzing them at pre-selected number of modulation indices. Optimal multi-h phase codes which produce the highest minimum Euclidean distance are presented according to the number of states. Three orders of multi-h signaling 2-h, 3-h, and 4-h signaling are considered in the optimal code search.
