Abstract

We have demonstrated an efficient scattered pilot channel tracking approach with a new polar-based intra-symbol frequency domain average (ISFA) for 16-QAM, 40-Gb/s PDM-CO-OFDM systems. This proposal could promise an relatively stable performance even under an rapidly time-varying environment. (C)2011 Optical Society of America
