Abstract :
Discrete multi-tone (DMT) and pulse amplitude modulation (PAM) are two attractive modulation techniques in intensity-modulation and direct-detection low cost 100Gb/s system. Experiment and simulation show that DMT and PAM have different tolerance to different distortions. By an experimentally verified simulation platform, the impacts of different distortions including white noise, colored noise and narrow-band interference on DMT and PAM are intensively investigated and discussed. It´s demonstrated that DMT outperforms PAM in most scenarios, especially with serious colored noise and narrow-band interference.
