Modified frequency and phase estimation for M-QAM optical coherent detection

A frequency estimation without removing modulated data phase is proposed for M-QAM coherent system. In addition, a group of weighted coefficients are introduced for M-QAM phase estimation, resulting in an increment of laser linewidth tolerance.
