| Popis: | This paper presents a link quality model for a wireless communication system with distributed turbo coding and lossy forwarding. The model maps the signal-to-interference-plus-noise ratio (SINR) of packet copies received from different links to a mutual information parameter and, in a second stage, converts it to a block error rate. We present the design and foundation of the model and validate its accuracy for different modulation and coding schemes over additive white Gaussian noise (AWGN) channels. The model accurately predicts the link-level performance at a low computational complexity and can be therefore used as an physical layer (PHY) abstraction for the computationally-intensive, simulation-based performance evaluation of various functionalities at higher protocol layers or at the system level. In order to illustrate the usage of the proposed model, we show the integration of the model into a protocol level simulator assessing the performance improvements of lossy forwarding and joint decoding. |
