Sebagai skema modulasi untuk komunikasi wayarles optik, terdapat MPolSK (pengkunci anjakan polarisasi berbilang peringkat) yang memodulasi keadaan polarisasi cahaya. MPolSK mempunyai masalah bahawa ia terjejas teruk oleh paksi polarisasi yang tidak sepadan. Walaupun MDPolSK (PolSK pembezaan berbilang peringkat) boleh mengatasi masalah itu, ia terdedah kepada bunyi bising, dan SERnya (kadar ralat simbol) merosot berbanding dengan MPolSK. Dalam kertas ini, kami mencadangkan satu jenis MDPolSK yang menganggarkan paksi polarisasi yang tidak sepadan dalam penerima. Kami menganalisis SER skim yang dicadangkan oleh simulasi komputer. Hasilnya menunjukkan bahawa skim yang dicadangkan tidak terjejas oleh paksi polarisasi yang tidak sepadan, dan ia menyediakan SER yang baik berbanding dengan MDPolSK konvensional. Di samping itu, kami mengubah suai buruj yang digunakan dalam skema yang dicadangkan untuk menambah baik SER.

Abstract: As a modulation scheme for optical wireless communication, there is MPolSK (multilevel polarization shift keying) that modulates a state of polarization of light. MPolSK has a problem that it is severely affected by mismatched polarization axes. Although MDPolSK (multilevel differential PolSK) can overcome the problem, it is susceptible to noise, and its SER (symbol error rate) degrades as compared to MPolSK. In this paper, we propose one kind of MDPolSK that estimates the mismatched polarization axes in the receiver. We analyzed SER of the proposed scheme by computer simulations. The result shows that the proposed scheme is not affected by the mismatched polarization axes, and it provides a good SER as compared to the conventional MDPolSK. In addition, we modified the constellation used in the proposed scheme to improve SER.
