碩士 === 國立暨南國際大學 === 通訊工程研究所 === 97 === In the MIMO system, using the selection combining technique can improve the performance of the STBC scheme. Therefore, the three research topics of this thesis are all related to the STBC scheme with selection combining. In the first research topic of this thesis, we study several selection criteria for the selection combining technique. We found that these selection criteria can result in the further performance improvements or can simplify the implementations. The second research topic of this thesis incorporates the transmit antenna selection into the selection combining technique. Simulation results show that such an integration of the receive antenna selection and the transmit antenna selection can further reduce the bit error probability. The selection combining technique needs to know the channel information, thus the third research topic of this thesis deals with the channel estimation for the selection combining technique. We found from simulation results that the accuracy of the channel information can affect the performance of the selection combining technique.
