  We study the changes in quantum Fisher information (QFI) values for one
quantum system consisting of a superposition of W and GHZ states. In a recent
work [6], QFI values of this mentioned system studied. In this work, we extend
this problem for the changes of QFI values in some noisy channels. We show the
change in QFI depending on noise parameters. We report interesting results for
different type of decoherence channels.
