Abstract :
Advanced modulation formats using higher-order amplitude- and phase-modulation have been recently used to achieve record capacity in long-haul optical transmission systems. In this work, we evaluate the receiver performance of five modulation schemes in a single-channel optical transmission scenario of 40 Gbit/s using numerical simulations. The well known Karhunen-Loeve expansion method for square-law detection is applied on the calculation of the bit-error rate for each receiver model
