Level Optimization of PAM-4 Transmission With Signal-Dependent Noise
A level optimization method for the 4-level pulse-amplitude modulation format is proposed. This optimization method is applicable to signal-dependent noise conditions such as the relative intensity noise and amplified spontaneous noise. The proposed optimization was verified by simulation results an...
