High spectral efficiency (SE) OFDM system based on multi-wavelet packets

We investigated the multiwavelet (MW) packet based coherent optical OFDM (CO-OFDM) system. We have shown that MW based CO-OFDM system offers high degree of flexibility and adaptivity in terms of data rate, modulation, and number of subcarriers. MW based CO-OFDM demonstrates better performance compared to conventional OFDM for a transmission distance of about 2000 km.
