A. Kanazawa et al., PRE-CLIPPING METHOD TO REDUCE CLIPPING-INDUCED DEGRADATION IN HYBRID ANALOG-DIGITAL SUBCARRIER-MULTIPLEXED OPTICAL-TRANSMISSION SYSTEMS, IEEE photonics technology letters, 7(9), 1995, pp. 1069-1071
The authors newly propose a pre-clipping method that can reduce the im
pairment due to LD clipping in hybrid analog/digital subcarrier-multip
lexed optical transmission for future interactive CATV systems. It is
experimentally confirmed that a CNR improvement of 1.3 dB is achieved
with the proposed method.
