| dc.description.abstract | This paper deals with Turbo Frequency-Domain Equalization (FDE) for Single Carrier (SC)-based block transmission, under full-Cyclic Prefix (CP) conditions. As in recent papers of the authors, the Turbo FDE technique considered here involve a linear FDE scheme and a soft cancellation of residual Inter-Symbol Interference (ISI). The contribution of Soft-In SoftOut (SISO) decoding for Turbo FDE performance is evaluated in detail,forclassesofconvolutionalcodingschemeswhichinvolvea rangeofcoderates(from R = 1 2 to R = 1)andconstraintlengths (from 2 to 16 states, in the R = 1 2 case). This evaluation includes a discussion on using either the ”extrinsic” or the ”full” SISO decoder’s information as an ”a priori” input to the frequencydomain equalizer, with appropriate comparisons. It also includes the comparison of achievable performances with easily computed matched-filter bounds, namely for R = 1 (the uncoded Bit Error Rate (BER) performance case). The main conclusion is that the advantage of using the full SISO decoder’s information increases with an increased code rate, obtained by code puncturing, or a reduced number of states for a given code rate. Using the full SISO decoder’s information, for soft ISI cancellation in Turbo FDE schemes, is always an appropriate choice. Moreover, in all cases, this choice provides close approximations to the matchedfilter bound performance after a few iterations. | pt_PT |
