Continuous phase FM with memory proves to be a powerful instrument of enhancing
GNSS signal spectral efficiency. It
is demonstrated that the partial response CPM is treatable as OQPSK with chip
overlapping in each quadrature stream and subsequent envelope normalization.
The combination product estimation is done. Spectral characteristics of partial
response CPM signal are presented.
