The performance of bandlimited offset-quaternary-phase-shift-keying (OQPSK) systems in the presence of noisy phase reference and additive Gaussian noise is analyzed. Expressions for error probability calculation are obtained. A new search method for computing the detection loss and the required SNR of the phase reference is proposed. It is shown that when the rolloff factor for the Nyquist filtering is large, OQPSK surpasses QPSK, but when the rolloff factor is small, QPSK surpasses OQPSK
