modeling and analysis of the packet-level loss process in wireless channels
Losses in real-time multimedia communications have a big impact on the quality experienced by users. In wireless networks, some application level mechanism of Forward Error Correction (FEC) is useful to protect the transmission. In order to adjust the configuration of FEC, a model of the packet-level loss process is required. This work proposes a methodology for the analysis of the loss process of packet-oriented communications using semi-Markov models, hierarchical Markov models, and Monte Carlo simulation. The methodology is applied to the analysis of HSDPA channels, and the models obtained are used to verify the performance of FEC implemented with Reed-Solomon codes.
