ABSTRACT

Continuous phase FM with memory proves to be a powerful tool of enhancing GNSS signal spectral efficiency. It is demonstrated that such modulation can be reduced to an equivalent offset QPM with chip overlapping in each quadrature stream and subsequent envelope normalization. The combination product estimation is done. Spectral characteristics of memory CPM signal are presented
