Abstract

The probability of symbol error (P_E) performance is studied for cross-polarized M-QAM (M-ary quadrature amplitude modulation) and L-QPRS (L-ary quadrature partial response signal) systems operating in the depolarization crosstalk and differential phase shift environment. Explicit general formulas are provided and results presented for dual-channel 4-QAM (QPSK-quadrature phase-shift keying) and 9-QPRS. It is demonstrated that the P_E varies with a period of 90° with differential phase shift and that L-QPRS systems are less sensitive to differential phase shift than the corresponding M-QAM systems; the sensitivity is measured by the ratio of maximum to minimum P_E
