digital sub-carrier multiplexing (DSCM) and show improved jitter performance using estimates from each subcarrier in cartesian co-ordinate compared with direct phase estimations in polar form.
We analyze timing phase estimation in high speed coherent optical communication with digital sub-carrier multiplexing (DSCM) and show improved jitter performance using estimates from each subcarrier in cartesian co-ordinate compared with direct phase estimations in polar form.
