Circle polarization shift keying (CPolSK) is a new modulation technique. It uses the state of polarization of an electromagnetic wave carrier as the information bearing parameter. This paper describes a modulation/demodulation method based on CPolSK with balance detection, and verifies its feasibility through theoretical analysis and computer simulation. Studies have shown that the optical system based on CPolSK techniques has unique advantages, such as in anti-atmospheric interference, higher data rate and lower bit error rate, greatly improving the reliability of communication. In the future, the PolSK technique has a broad space for development and application prospects in the space laser communications. |
