Multiband DFT-spread-OFDM equalizer with overlap and-add dispersion compensation for low-overhead and low-complexity channel equalization
17 March 2013
We describe a multi-band DFT-spread-OFDM equalizer that combines overlap-and-add dispersion compensation with OFDM demultiplexing for reduced guard interval and lowered DSP complexity, and demonstrate it in the transmission of a 22-Gbaud signal over 6400-km SSMF.
