VII. CONCLUSION
The paper presents a novel concept in the field of digital communication by exploiting circular polarization as a characteristic to modulate data. This is different from conventional approaches that modulate data using amplitude,
frequency or phase of electromagnetic carrier as modulation attributes. Circular Polarization Modulations for 2, 4 and 8
states have been presented with thorough concept of symbol encoding, constellation, modulation, demodulation and the
waveforms of the propagating carrier. The proposed CPmodulation techniques provide inherent benefits of circular
polarization as well as diversity gain in fading channels.
