N2 - The convolutional coding combined with continuous phase modulation (CPM) is known for its good tradeoff between coding gain and bandwidth. The multi-h modulation, i. e. , the scheme in which plural modulation indices are in cyclical use, is introduced to obtain higher power efficiency. However the study of the combination of convolutional coding multi-h scheme has not been reported yet. In this study, we consider the combination of convolutional coded CPM with multi-h modulation to achieve larger Euclidean distance. We found that, in some cases, our proposed convolutional coded multi-h CPM can give considerable gains compared with those of conventional single-h scheme.
