| Summary: | 碩士 === 國立暨南國際大學 === 電機工程學系 === 102 === With a higher system performance, the cooperative communication has been wildly discussed among the recent researches. Concerning within the relay location and the power allocation in the cooperative communications, the major purpose of this work is to evaluate the system performance under the related limitation. According to the theoretical derivation and simulation results, one can find that the diversity gain in the communication could be obtained with the relay station in decode and forward mode. While the path loss from the source station to destination station is large, the relay station could benefit to the transmission performance. Besides, concerning of propagation distance from the source station to destination station, this work adopts the outage probability as the threshold and analyzes the maximum transmission length. The relay deploy scheme could be applied with this significant consequence. Moreover, applied the cooperative communication to the satellite system, this work evaluates the three relay-destination matching schemes. The probability of successful matching depends on the number of destination stations.
This work contributes the cooperative communication with the tradeoff between the relay location and the power allocation. Also, the research on maximum transmission length in the cooperative communication system could provide an important reference to the relay deploy schemes.
