  • Abstract
    A model is developed for finding codes for differentially demodulated continuous phase frequency-shift keying with modulation index h=1/M, where M is the size of the symbol alphabet. The results of codes searches show that there is very little loss in squared Euclidean distance when comparing differential codes with coherent codes
