Abstract

In this paper, we compare performances of the constant modulus algorithm (CMA) and data-aided time domain equalization (DA-TDE) algorithm for mode demultiplexing in few mode transmission systems. Simulation results of \(4\times 56\ \hbox {Gbit/s}\) QPSK mode-division multiplexed system show that the maximum required OSNRs with CMA are less than that of DA-TDE by 0.8 and 4.6 dB for high maximum coupling coefficient of 0.15 and 0.20.
