ABSTRACT:
Embodiments for non-coherent phase differential and multiple orthogonal signal modulation/demodulation are disclosed. One illustrative embodiment may include: a method for non-coherent reception of a signal with spectrum spreading, comprising performing a multiple orthogonal signal demodulation operation on the signal; performing a phase differential demodulation operation on the signal; and combining the results of the multiple orthogonal signal demodulation operation on the signal and the phase differential demodulation operation on the signal.
