# Performance comparison of DA-TDE and CMA for MIMO equalization in multimode multiplexing systems

Performance comparison of DA-TDE and CMA for MIMO equalization in multimode multiplexing systems 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 $$4\times 56\ \hbox {Gbit/s}$$ 4 × 56 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

### 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 $$4\times 56\ \hbox {Gbit/s}$$ 4 × 56 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.
