碩士 === 國立臺灣海洋大學 === 通訊與導航工程系 === 96 === As the demand of the high speed wireless network for users, it is expected that WiMAX system based on IEEE 802.16 and technical standard is wide concerned in recently year. But the man who is in the bounded of the base station or the urban, the low quality of signal will reduce the transmission rate, it is hard to guarantee the high speed data rate transmission for telecommunication industry. The text will investigate the multi-hop decision algorithm based on the Markov Chain, and use the algorithm of Markov Chains as the model of the system gateway. According to the Absorbing Markov Chains, using the method can estimate the outage probability of Relay-Hopping. Besides, combing the concept of Markov Chains with the Relay- Hopping technique which can increase the speed of transmission, uses the form matrix of Canonical computing the Standard deviation and the variance of the transition number as the judgment after the decision of Relay-Hopping. For example, use this method to improve the signal blocking probability, and to ensure the communication quality as IEEE802.16m requirements.
