| Abstract(in English) | In a bandlimited QPSK transmission system,pattern jitter exists at the output of carrier recovery circuit using 4-th power device. In this paper,an exact representation of autocorrelation function of its output phase variation is obtained assuming a QPSK signal of an arbitrary waveform and corrupted with bandlimited Gaussian noise.The power spectral density of random phase jitter and rms jitter of the recovered carrier are also obtained. As the extreme example of severe bandlimitaiton,the case of an ideal Nyquist transmission scheme where the transmission bandwidth is equal to clock rate is analyzed to obtain the power spectral density and the rms jitter.Their three components;Signal×Signal,Si gnal×Noise and Noise×Noise components are numerically calculated. The Signal×Signal component,which corresponds the pattern jitter,e xists independent of SNR and dominates as SNR exceeds 12 bB. |
