Integration time of the correlation receiver for a Nyquist optical time-division multiplexing (OTDM) scheme is limited by the multiplicity of the OTDM scheme. We investigate the signal degradation caused by the finite integration time of the correlation receiver. The signal degradation factor is analyzed by separating it into noise resistance degradation and inter-symbol interference. We also conduct numerical simulations to estimate the required multiplicity number and roll-off factor for suppressing the signal degradation.
