Abstract:

With the rapid development of wireless technology,the wireless communication offers great flexibility and convenience to mobile users.However,due to the slow/fast fading caused by multipath effect,the transmission rate of wireless fading channel is unstable,which will affect the transmission delay and communication quality.In literature,the wireless fading channel is also called Markov channel.The transition of channel state is controlled by a Markov chain.A detailed analysis was given for a three-state Markov channel.The whole system was modeled as an M/MMSP/1 queuing system considering the arrivals and services of packets.By defining conditional start service probability and conditional expected delay,the analytical expressions of mean service time and mean waiting time of packets were given using the state transition matrix.At last,by discussing the mean waiting time in limiting cases,the factors that affect the delay were given.

Key words: Markovchannel, statetransitionmatrix, startserviceprobability, meanwaitingtime
