Abstract
A method and apparatus of predicting link quality of a link are disclosed. One exemplary method includes a receiver receiving multi-carrier modulated signals over a period of time. A signal to noise ratio (SNR) for each received sub-carrier is estimated. An ordered sequence of the signal to noise ratios (SNR)s are constructed based on interleaving of the multi-carrier modulated signals, wherein an order of the interleaving is used to set the ordered sequence of the signal to noise ratios (SNR)s. The receiver estimates link packet error rate (PER) based upon knowledge of encoding of the multi-carrier modulated signals used during transmission and the ordered sequence.
