在本論文中,我們研究在多輸入多輸出(multiple-input multiple -output,MIMO)正交分頻多工(orthogonal frequency division multiplexing,OFDM)系統下使用約束自適應性馬可夫鏈蒙特卡羅(constrained adaptive Markov chain Monte Carlo,CAMCMC)最佳化方法應用在不同天線選擇(antenna selection)演算法上,其通道容量和系統錯誤率逼近於窮舉(exhaustive search,ES)最佳化方法,而CAMCMC計算的複雜度(complexity)和ES比較,CAMCMC最佳化方法達到ES最佳化方法的10%左右。
透過模擬,使用不同的天線選擇演算法,選擇不同的天線個數,改變環境參數,我們發現CAMCMC效能皆逼近於ES,效能上雖然無法完全相同,但是卻降低相當可觀的計算複雜度。

In the thesis, we study of antenna-selection algorithm based on constrained adaptive Markov chain Monte Carlo(CAMCMC) optimization method with different antenna selection criteria in multiple-input multiple-output-orthogonal frequency division multiplexing(MIMO-OFDM).Show that both the channel capacity and the system BER by the CAMCMC algorithm are close to the exhaustive search(ES). We further demonstrate that the complexity of CAMCMC can be achieved with less than 10% of the complexity of ES rule.
Simulate the different antenna-selection algorithm, and change the selected antennas…We find the performance of the CAMCMC algorithm are close to the ES, though the performance can’t be the same, but CAMCMC reduce a lot of computational complexity compare with ES.
