| Abstract: | An improved genetic algorithm(GA) for antenna array optimization in multi-input multi-output(MIMO) system was presented.The relationship between capacity and spatial domain correlation was explored based on the correlation model of uniform linear array and uniform circular an-tenna array.The effects of angle of arrival(AOA),spread angle and antenna interval on the correlation were compared.A constructed matrix consisted of correlation coefficients was analyzed.The distribution of limit-length,non-uniform 4-... |
