Abstract
We studied the behavior of an iterative receiver using protograph based LDPC codes (PG-LDPCC) in an UWB short range communication system. An EXIT-Chart-Analysis is applied by means of density evolution of protographs. We show that AWGN-optimized protograph ensembles perform also well on frequency-flat UWB channels, outperform rate-compatible punctured convolutional codes (RCPC), but degrade with increasing intersymbol interference (ISI). Slight modifications of the underlying protograph can improve this performance, but lead to a trade-off between the minimum required SNR and the minimum achievable BER. It is shown that both thresholds can be predicted by the applied tools.
