| Summary: | 碩士 === 國立雲林科技大學 === 電子與資訊工程研究所 === 99 === Recently, Multiple-input multiple-output (MIMO) systems was interested due to its advantage of increasing the spectral efficiency using arrays of transmit and receive antennas with spatial processing. In addition, placing a relay station between the base station and the mobile station based on the concept of cooperation diversity systems, thereby increasing the coverage of wireless transmission and reliability.
In this thesis, we applied a Constrained Cross Entropy Optimal (CCEO) method in antenna selection at each terminal in order to reduce the whole system’s resource costs and computational complexity, also, the Zero Forcing (ZF) method for symbol detection was conducted in this thesis to obtain the Bit Error Rate (BER). Then, we compared the channel capacity and the BER acquired through the CCEO method to Exhaustive Search (ES) method, the results showing that the required complexity for CCEO is significantly lower than that for ES.
