CHANNEL ESTIMATION APPARATUS OF 16APSK MODULATION METHOD AND METHOD THEREOF

摘要

The present invention includes a demapper which demaps inputted data; a turbo decoder which turbo-decodes a signal demapped by the demapper; and a symbol estimating part which maps data decoded by the turbo decoder to one of the reference symbols of a16APSK modulation method by using LLR calculation, and inputs it to the demapper. So, the receiving performance of a receiver can be improved.;COPYRIGHT KIPO 2016
