Comparison of finite-state models for simulating the DVB-H link layer performance

摘要

Digital video broadcasting for handheld terminals (DVB-H) is a broadcast system designed for high-speed data transmission in highly dispersive mobile channel conditions. In this paper, various finite-state models for simulating the transport stream packet error behavior of a DVB-H system operating in a multipath channel environment are presented and evaluated. The results from finite-state models are compared to measurement results. The model evaluation focuses on the accuracy of the models in replicating the high-order statistical properties of measured link layer transport stream error traces. Furthermore, the significance of these high-order error statistics such as variance in error burst length in simulating the link layer frame error rate of DVB-H is considered.
