Abstract:

The research on the transmission efficiency of data packet in Rayleigh fading channel is presented in the paper where the radio channel is modeled according to the GillbertElliott model. The research shows that the transmission efficiency depends on the packet size and the status of the channel where the packet is transmitted. Based on the founding,the optimal length of data packet during the transmission is deduced. The corresponding simulated is executed to testify the results of analysis. According to the results obtained from analysis and simulation, the dynamic adjustment mechanism on the packet size aimed at different service and channel condition is proposed.

Key words: GfillbertElliott, Markov, optimal frame size, data packet, transmission efficiency
