Detection with erasure for error‐propagation mitigation in decode‐and‐forward relaying with general pulse amplitude‐modulated/quadrature amplitude‐modulated signals
Abstract:In the research of decode-and-forward (DF) cooperative communications, it is often supposed that the included relay only transmits correctly decoded signals. This simplifies the analysis of DF cooperation. However, in practical circumstances, erroneous messages may be forwarded which makes the decision at the destination even worst. In this study, the authors formulate a special detection way, named 'detection with erasure', to make certain that the relay-forwarded signals are mostly correct. Specifically, whe… Show more
