Cut-off frequency and number of quantization bits required for correlation receiver in Nyquist OTDM scheme

Abstract

We investigate the effect of the cut-off frequency and number of quantization bits of analog-to-digital converters on the signal quality in a Nyquist optical-time-division-multiplexing scheme using the impulse response of a correlation receiver. The cut-off frequency and number of quantization bits required at a baud rate of 160 GBd are determined through numerical simulations.
