Title:
コヒーレント受信機における微細周波数オフセット推定のための推定精度及びロバスト性の向上した方法及び装置
Document Type and Number:
Japanese Patent JP6393836
Kind Code:
B2
Abstract:
The present disclosure provides a method and system for fine estimation of a local oscillator frequency offset of a received signal at a coherent receiver, by evaluating the probability mass function (PMF) of the signal phase of output symbols at different frequencies. At frequencies other than the actual frequency offset, the signal phase is uniformly distributed in [−π,π] such that the summation of a function of PMF values where the function is convex or concave between 0 and 1 can be utilized to determine an a frequency offset to be used by the coherent receiver.
