An improved unitary-spread OFDM is proposed to mitigate the fiber nonlinearity with small computational complexity. The simulation results show that U-S OFDMs based on two orthogonal transforms have better fiber nonlinearity tolerance than plain OFDM.
We study the dynamic bid optimization problem via a primal dual approach. In the case we have no information about the distribution of queries, we reconstruct the ln(U/L) + 1 competitive algorithm proposed in [ZCL08] through a systematic way and showed the intuition behind this algorithm. In the case of random permutation model, we showed that the learning technique used in [DH09] can give us a (1...
We experimentally demonstrate a novel decision-aided maximum likelihood phase estimation in an 8-Channel 42.8-Gbit/s DWDM coherent PolMux QPSK system. The results show that our proposed algorithm can achieve a comparable performance as the Mth-power while having much lower computational complexity.
