Analysis of the power line channel estimation error based on comb-type pilot arrangement
Résumé
In this paper, we analyze the error of channel estimation using the pilot tones associated with interpolation technique. Our method is based on a unified mathematical decomposition of the channel estimation error, which takes both the signal-to-noise ratio at pilot sub-carrier locations and the interpolation kernel used into account. This method has been recently proposed by the authors and illustrated over a channel model. We complete here the previous analysis and provide news results over a power line severe real channel.
